Term
| What is the most common cause of an arrhytmias? |
|
Definition
coronary heart disease, and other conditions that damage cardiac tisse, including heart valves disorders, heart failure and damage from a heart attackt |
|
|
Term
| Can antiarrhytmic drugs cause arrhythmias? |
|
Definition
|
|
Term
| Describe Atrial Fibrilaation (A. Fib, AF) |
|
Definition
Atria contract abnormally. A. Fib carries a high risk of cot formation. Chronic A. Fib requires anticoagulation therapy
|
|
|
Term
|
Definition
| A. flutter often converts to atrial fibrillation |
|
|
Term
| A prolonged QT interval is a marker for what? |
|
Definition
ventriulcar tachyarrhythmias, including torsades de pointes (can result in sudden death) |
|
|
Term
|
Definition
Is a measure of how long it takes the heart to re-polarize (recharge) after each beat.
Prolonged QT interval leaves the patient vulnerable to arrhytmias
|
|
|
Term
Medications can be used to convert the patient from the arrhytmia to normal sinus rhythm (NSR), or used to maintain NSR, or to reduce the heart rate. Is ventricular rate control as effective as rhythm control? |
|
Definition
Recent trials have shown that ventricular rate control is as effective as rhythm control with cardio-version and antiarrhytmic drugs
|
|
|
Term
Which is first line in correcting arrhythmias: ventricular rate control or rhythm control? |
|
Definition
|
|
Term
| Which drugs are used in rate control? |
|
Definition
Drugs used for rate control in atrial fibrillation, or A. Fib (the most common type of arrhythmia) are beta - blockers, non-dihydropyridine calcium channel blockers (diltiazem and verapamil) and digoxin, all of which reduce heart rate
|
