Ventricular tachycardia
What do you call an arrhythmia that is too slow?
Bradyarrthymia
Why is Bradyarrthmia too slow?
Arrhythmia is <60/min
What do you call an arrhythmia that is too fast?
Tachyarrythmia
Why is tachyarrythmia too fast?
Arrhythmia is >100/min
What is the treatment of ventricular fibrillation?
Heart valve surgery
Transplant
Where on the body will you find a pacemaker?
Left upper chest wall
What does ICD stand for?
Implantable cardiovascular defibrillator
What side of the heart is most commonly affected by valvular heart disease?
The left side
What valves are affected in valvular heart disease?
Aortic valve
Mitral valve
What can cause VHD?
Ineffective endocarditis
Rheumatic fever
Is VHD age related?
Yes
What are the 2 processes of VHD?
Regurgitation
Stenosis
What is regurgitation?
Loss of valve integrity
Becomes floppy
Leaks
What is stenosis?
Narrowing of valve
Obstruction of flow
What can regurgitation and stenosis lead to?
Heart failure
What is the treatment for VHD?
Medication
Surgery
TAVI
What are some dental implications to VHD?
Patient’s on anticoagulant
Risk of ineffective endocarditis
Ineffective endocarditis can be induced by invasive procedures. How does this affect dental treatment?
Dental procedures + tooth brushing may lead to ineffective endocarditis
What are the types of congenital heart disease?
Atrial septal defect
Ventricular septal defect
Patent ductus arteriosclerosis
Coarctation of the aorta
Tetralogy of fallot
What is a atrial septal defect?
Hole in septum
Is there risk of ineffective endocarditis with atrial septal defect?
No
What is ventricular septal defect?
Hole in ventricular septum
Is there risk of endocarditis with ventricular septal defect?
Yes
What is patent ductus arteriousus?
Ductus arteries is part of foetal circulation - closes at birth
Is there risk of endocarditis with patent ductus arteriousus?
Yes
What is coarctation of the aorta?
Narrowing of the aorta at the site on embryonic ductus arteries
Is there risk of endocarditis with coarctation of the aorta?
Yes
