Cardiac arrhythmias may be seen in individuals with known cardiovascular disease (i.e., coronary artery disease (CAD) or valvular abnormalities) or even in those without known cardiac illnesses. The spectrum of cardiac arrhythmias varies between more self-limited or minimally symptomatic findings such as palpitations, which may be associated with premature supraventricular or ventricular beats that many experience, to the more worrisome ventricular fibrillation, a known cause of sudden cardiac arrest for which emergency cardiac resuscitation is required. of cardiac arrhythmias varies between more self-limited or minimally symptomatic findings such as palpitations, which may be associated with premature supraventricular or ventricular beats that many experience, to the more worrisome ventricular fibrillation, a known cause of sudden cardiac arrest for which emergency cardiac resuscitation is required.
