Question 30

Sinus arrythmia

Answer 30

Sinus rhythm but with quickening and slowing of impulse formation in the SA node resulting in slight beat-to-beat variation of rate.

Question 31

Sinus arrest

Answer 31

A sinus rhythm but with intermittent failure of either SA node impulse formation or AV node conduction that results in occasional complete absence of P or QRS waves.

Question 32

Premature atrial contractions (PAC)

Answer 32

When an ectopic focus (abnormal pacemaker site) in the atrium initiates an impulse before the SA node. P wave is premature with abnormal configuration. Very common and generally benign but may progress to atrial flutter, tachycardia, or fibrillation. May occur from caffeine, stress, smoking, alcohol, and any type of heart disease.

Question 33

Atrial flutter

Answer 33

Atrial tachycardia, atrial rate of 250-350 bpm. Ventricle rate depends on AV node conduction. Saw tooth shaped P waves. Occurs with valvular disease (especially mitral), ischemic heart disease, cardiomyopathy, hypertension, acute MI, chronic obstructive lung disease, and pulmonary emboli. Signs & symptoms include palpitations, lightheadedness, and angina. Stagnation of blood can predispose to thrombi in the atria.

Question 34

Atrial fibrillation

Answer 34

Common arrhythmia where atria are depolarized between 350-600 bpm. Irregular undulations of ECG baseline without discrete P waves. Occurs in healthy hearts and those with coronary artery disease, hypertension, and valvular disease. Symptoms include palpitations, fatigue, dyspnea, lightheadedness, syncope, and chest pain. Stagnation of blood can predispose to thrombi in the atria.

Question 35

1st degree atrioventricular block

Answer 35

PR interval longer than 0.2 seconds but relatively constant from beat to beat. No symptoms or significant changes in cardiac function. May be caused by medications that suppress AV conduction.

Question 36

2nd degree atrioventricular block

Answer 36

Impulse between atria and ventricles fail intermittently. 2 major types: Mobitz type I block (Wenckebach block) and Mobitz type II block. Mobitz I - progressive prolongation of PR interval until one impulse is not conducted (generally benign) Mobitz II - consecutive PR intervals are the same and normal followed by nonconduction of one or more impulses (more serious condition)

Question 37

3rd degree atrioventricular block

Answer 37

Complete heart block, all impulses blocked at AV node and none transmitted to ventricles. Atria and ventricles paced independently; atrial rate > ventricular rate. Medical emergency requiring pacemaker. May faint if ventricular rate too slow. Causes include degenerative changes of the conduction systems, digitalis, heart surgery, and acute MI.

Question 38

Premature ventricular complex (PVC)

Answer 38

Premature ventricular depolarization due to an ectopic focus. P wave usually absent and QRS complex has a wide and aberrant shape. Bigeminy - Normal sinus impulse followed by a PVC. Trigeminy - PVC occurs after every two normal sinus impulses. Common arrhythmia that occurs in healthy and diseased hearts. Pt may be asymptomatic or have palpitations. Causes include anxiety, caffeine, stress, smoking, and all forms of heart disease.

Question 39

Ventricular tachycardia (v-tach)

Answer 39

3 or more consecutive PVCs at a ventricular rate of > 150 bpm P waves absent and QRS complexes are wide and aberrant V-tach longer than 30 seconds is life-threatening and requires immediate medical interventions Pt unable to maintain adequate blood pressure and eventually become hypotensive May progress to ventricular fibrillation, causing cardiac arrest Causes include MI, cardiomyopathy, and valvular disease

Question 40

Ventricular fibrillation (v-fib)

Answer 40

Ventricles do not beat in coordinated fashion but fibrillate or quiver asynchonously and ineffectively No cardiac output; patient becomes unconscious ECG shows fibrillatory waves with irregular pattern May require immediate defibrillation Medications to support circulation and intravenous antiarrhythmic agents Causes include heart disease of any type, MI, and cocaine use

Question 41

Answer 41

Ventricular standstill with no rhythm ECG records a straight-line pattern Requires immediate CPR and medications to stimulate cardiac activity Causes incline MI, ventricular rupture, cocaine use, lightning strikes, and electrical shock

Question 42

Answer 42

Subendocardial ischemia, digitalis toxicity, or hypokalemia | Segment is evaluated as a deviation from baseline in mm.

Question 43

ST segment elevation

Answer 43

Earliest sign of acute transmural infarction Can also indicate benign early repolarization pattern in a normal heart Deviations from isoelectric baseline expressed in mm.

Question 44

Abnormal Q wave

Answer 44

Marker of infarction; signifies loss of positive electrical voltages due to necrosis. Significant or abnormal Q wave is longer than 0.04 msec and larger than 1/3 the amplitude of the R wave.

Question 45

T wave inversion

Answer 45

Occurs hours or days after an MI as a result of a delay in repolarization produced by the injury. May also occur with R and L bundle branch blocks, after a CVA, and normal juvenile T wave pattern in children and some adults.

Question 46

Exercise Stress Test

Answer 46

ECG, BP, HR, and symptoms are monitored while exercise intensity is increased to monitor tolerance. Negative test indicates low probability of coronary artery disease. Positive test indicates high probability of coronary artery disease. Can determine aerobic exercise prescription.

Question 47

Answer 47

Passively DF the ankle with knee straight. Positive if pain in the calf or popliteal space.

Question 48

Mediate Percussion

Answer 48

Act of tapping surface of body to identify areas of altered density. Use middle finger to strike intercostal spaces anteriorly and posteriorly, comparing sounds from each space from left to right. Sounds of tissue of high to low density: Flat or dull - Sound elicited by percussion of thigh muscles; in the upper lung, suggests neoplasm, atelectasis, or consolidation. Resonance - percussion sound from normal air-filled lung Hyperresonance - Emphysematic lung, pulmonary emphesema, or pneumothorax Typany - hollow sound; indicates large pneumothorax

Question 50

Pulmonary Function Testing (PFT)

Answer 50

Measures volume or flow of air during inhalation and exhalation. Pt exhales into spirometer as hard and as fast as possible for 6 seconds until no more air can be exhaled. Obstructive ventilatory impairment: - Decreased expiratory flows - FEV1/FVC <70% - Pathologies include asthma, emphysema, and chronic bronchitis Restrictive ventilatory impairment: - Reduced lung volumes (TLC, TVC, FEV1) and relatively normal expiratory flow rates - FVC reduced and FEV1/FVC is normal or >80% - Pathologies include interstitial lung disease, pleural diseases, chest wall deformities, obesity, pregnancy, neuromuscular disease, and tumor

Question 51

Pulse Oximetry

Answer 51

Estimates percent of arterial oxygen saturation of hemoglobin. SpO2 is +/-4% of actual arterial O2 saturation. If SpO2 <90% in acutely ill patients or <85% in patients with chronic lung disease, activity should be stopped.

Question 52

Rate Pressure Product (RPP)

Answer 52

Index of myocardial oxygen consumption and coronary blood flow. Can be compared with onset of angina or development of ECG abnormalities. RPP = HR X SBP Usually reported as a 2 digit number x 10^3 May be used to prescribe exercise, keeping intensity below RPP value to reduce risk of angina

Question 53

Rate of Perceived Exertion (RPE)

Answer 53

Original 6-20 scale and revised 0-10 Borg scales. RPE of 13-14 represents about 70% of maximum heart rate during exercise. RPE of 11-13 represents the upper limit of prescribed training heart rates early in cardiac rehab.

Answer 62

Measuring tape placed at level of iliac crest at end of normal exhalation. Increased risk for type 2 diabetes, dyslipidemia, hypertension, and cardiovascular disease associated with circumference > 102 cm (40 in) for men and 88 cm (35 in) for women. Individuals with waist circumferences greater than these values should be considered one risk category above that defined by their BMI.
