Atrioventricular block
|
Description:
Intermittent or absent conduction between the atria and ventricles. Commonly occurs at the AV node or bundle branch system. Potential Cause: beta blockers, verapamil, endocarditic, MI |
|
|
Sick sinus syndrome
|
Description:
SA node block or SA node dysfunction, it patients suffering from severe weakness, dizziness. Treatment usually requires a pacemaker. Potential Cause: myocardial ischemia, inflammatory myocardial disease, digoxin toxicity. |
|
|
Arterial fibrillation
|
Description:
common sustained arrhythmia that is characterised by a disorder in electrical activity in atria causing fast irregular ventricular response. Potential Cause: elderly age, idiopathic, myocardial infarction, cardiac surgry |
|
|
Arterial flutter
|
Description:
arterial tachycardia characterised by contraction rate of 230-380/min with ventricular contraction in 1:2, 1:3, or 1:4 Potential Cause: often unknown, thyroid dysfunction, chronic hypertension, heart disease |
|
|
Supraventricular tachycardia
|
Description:
Arterial tachycardia and arrhythmias arising from AV junction. Potential Cause: hypoxia, electrolyte and acid base imbalances, enlarged atria, digoxin toxicity |
|
|
Premature ventricular ectopics
|
Description:
Ectopics Potential Cause: caffeine, stress, alcohol |
|
|
Ventricular tachycardia
|
Description:
>100 beats per min Potential Cause: acute myocardial infarction |
|
|
Torsades de pointes
|
Description:
characterised by a prolonged ventricular action potential (Q-T) interval Potential Cause: electrolyte disturbances for a number of drugs and drug classes. Amiodarone, disopyramide, sotalol, methadone, tricyclics antidepressants. |
