Ventricular tachycardia is the most disconcerting dysrhythmia for a patient with a history of myocardial ischemia, as it can quickly lead to ventricular fibrillation and sudden cardiac arrest. Sinus bradycardia and sinus dysrhythmias are relatively common and may not be a significant concern in this patient population. Atrial fibrillation can also be problematic, but it is not typically as immediately life-threatening as ventricular tachycardia.
