What is a heart block? Explain the three different types of heart block. First-degree Second-degree Third-degree

Disease of the electrical system of the heart, which controls activity of heart muscle FD - Atrioventricular (AV) block in which atrial electrical impulses are delayed by a fraction of a second before being conducted to the ventricles SD - AV block in which only some atrial electrical impulses are conducted to the ventricles TD - AV block in which no electrical impulses reach the ventricles; also called complete heart block (CHB)

What occurs when the heart is unable to pump enough blood flow to meet the needs of the body and can cause a number of symptoms, such as shortness of breath, leg swelling, and exercise intolerance?

Heart Failure (HF)

What is hypertension?

Consistently elevated blood pressure, causing damage to the blood vessels and, ultimately, the heart -tension = to stretch

Sever, sudden vasoconstriction and spasm in fingers and toes followed by cyanosis after exposure to cold temperature or emotional stress; also called Raynaud phenomenon

What is rheumatic heart disease?

Streptococcal infection that cause damage to the heart valves and heart muscle, most commonly in children and young adults. This causes stenosis of the heart valve eventually leading to valve replacement. rheu = flow

What is a stationary blood clot formed within a blood vessel or within the heart, commonly causing vascular obstruction?

Thrombus; also called a blood clot

What is a formation of a blood clot (thrombus) in one of the deep veins of the lower legs?

Deep vein thrombosis (DVT)

Diagnostic Procedures What is the insertion of a small tube (catheter) through a vein or artery, usually of an arm (brachial approach) or leg (femoral approach); the tube is threaded through a blood vessel until it reaches the heart; used to inject a contrast medium for imaging, diagnosing abnormalities, obtaining blood samples, or measuring pressure within the heart, and often includes interventional procedures, such as angioplasty and atherectomy?

Cardiac catheterization

Diagnostic Procedures What is a battery of blood tests performed to determine the presence of cardiac damage?

Cardiac enzyme studies Cardiac enzyme studies measure the levels of enzymes and proteins that are linked with injury of the heart muscle. The test checks for the proteins troponin I (TnI) and troponin T (TnT).

Diagnostic Procedures What is a US technique that records blood flow velocity (speed) to image major blood vessels (arteries or veins in arms, neck, legs, abdomen) to detect obstructions caused by atherosclerotic plaques in patients at risk for a stroke; also called ultrasonography using sound pitch?

Doppler ultrasonography Same device used with pregnancy US

Diagnostic Procedures What is a ultrasound technique used to image the heart and evaluate how the heart’s chambers and valves are working and to diagnose and detect pathological conditions?

Echocardiography (ECHO)

Diagnostic Procedures What is a creation and study of graphic recordings produced by electrical activity generated by the heart muscle; also called cardiography?

Electrocardiography (ECG, EKG)

Diagnostic Procedures What is a Holter monitor?

Monitoring device worn by a patient that records electrocardiograph readings (usually 24 hours) on a portable recorder while the patient conducts normal daily activities Smaller, portable recording devices are now being used and are taped to the chest or worn on the wrist.

Diagnostic Procedures What is a ECG taken under controlled exercise stress conditions (typically using a treadmill) while measuring oxygen consumption? ECG that uses a radioisotope to evaluate coronary blood flow?

Stress Test Nuclear stress test

Diagnostic Procedures What is a blood test that measures protein released into blood by damaged heart muscle (not skeletal muscle) and is a highly sensitive, specific indicator of recent myocardial infarction (MI)?

Troponin I

Medical and Surgical Procedures What is a surgery that opens a blocked artery by inflating a small balloon within a catheter to widen and restore blood flow in the artery?

Angioplasty

Medical and Surgical Procedures What is the restoration of normal heart rhythm by applying an electrical countershock to the chest by using a device (defibrillator); also called defibrillation?

Cardioversion

Medical and Surgical Procedures What is a bypass surgery in which peripheral veins are removed, and each end of the vein is sutured onto the coronary artery to create new routes around narrowed and blocked arteries, allowing sufficient blood flow to deliver oxygen and nutrients to the heart muscle?

Coronary artery bypass graft (CABG)

Medical and Surgical Procedures What is a device used to administer a defibrillating electrical shock to restore normal heart rhythm? What is a surgically implanted electrical device that continuously monitors and corrects potentially fatal arrhythmias by delivering low-energy shocks to the heart; also called implantable cardioverter defibrillator (ICD)? What is a portable computerized device that analyzes the patient’s heart rhythm and delivers an electrical shock to stimulate a heart in cardiac arrest?

Defibrillator Automatic implantable cardioverter-defibrillator (AICD) Automatic external defibrillator (AED)

Medical and Surgical Procedures What is the surgical removal of the lining of an artery? What is the removal of plaque (atherosclerosis) and thromboses from an occluded carotid artery to reduce the risk of stroke?

Endarterectomy Carotid endarterectomy

Medical and Surgical Procedures What is the treatment of large varicose veins in the legs, in which a laser fiber is inserted directly into the affected vein to heat the lining within the vein, causing it to collapse, shrink, and eventually disappear; also called endovenous laser ablation (EVLA)?

Endovenous laser therapy (EVLT)

Medical and Surgical Procedures What is sclerotherapy?

Chemical injection into a varicose vein that causes inflammation and formation of fibrous tissue, which closes the vein

Medical and Surgical Procedures What is valvuloplasty?

Insertion of a balloon catheter in a blood vessel in the groin through the aorta and into the heart to widen a stenotic (stiffened) heart valve and increase blood flow; also called percutaneous valvuloplasty

Pharmacology What prevents clotting or coagulation of blood? What slows the heart rate and reduces the force with which the heart muscle contracts, lowering blood pressure? What relieves chest pain associated with angina and ease symptoms of heart failure (HF)? What reduces cholesterol levels in blood and block production of an enzyme in the liver that produces cholesterol? What dissolves (lyse) blood clots in a process known as thrombolysis?

Anticoagulants Beta blockers Nitrates Statins Thrombolytics

What is the narrowing of the coronary arteries resulting in failure of the arteries to deliver an adequate supply of oxygenated blood to the heart muscle? What types of procedures would be used as treatment?

Coronary artery disease (CAD) heart muscle = myocardium Angioplasty and coronary artery bypass graft

What is a common form of atherosclerosis?

Arteriostenosis, usually caused by atherosclerosis

When the myocardium is getting a decreased supply of oxygenated blood resulting in CAD, what is this condition known as? What happens when there is a total or almost total occlusion

Ischemia Ischein = to suppress emia = pertaining to blood The myocardium dies resulted in infarction or death of tissue causing a heart attack or myocardial infarction (MI).

What do normal healthy veins have and are strong enough to withstand lateral pressure of blood exerted on them in which allows flow to the heart in one direction? What are incompetent veins that are dilated from long periods of pressure that prevent closure of the valves in blood vessels in which they become damaged and then do not close properly?

Competent valves Varicose veins, also known as varicosities. This pooling causes varicosities that contribute to enlarged, twisted superficial veins, called varicose veins.

Why do varicose veins appear blue, bulging, and twisted?

Because of oxygenated blood.

If you have varicose veins, what are you increased risk for?

Thrombosis Besides incompetent valves, varicose veins result from occupations that require prolonged standing or sitting, which causes pressure on the valves in the veins of the lower legs. Varicosities may also occur during pregnancy as the enlarging uterus increases pressure on the leg veins, compromising the free flow of blood in the lower extremities. Last, there seems to be a family tendency to develop varicose veins. Treatment consists of sclerotherapy and surgical interventions, such as endovenous laser ablation (EVLA) of the greater saphenous (large) veins in the legs and microphlebectomies of the lesser saphenous (small) veins. Stripping and ligation of varicose veins is less commonly performed.
