What are the potential clinical causes of sudden, self-limiting runs of rapid heartbeats (approximately 15 beats) at rest in a patient with a history of supraventricular tachycardia (SVT), moderate mitral valve prolapse (MVP) with mitral and tricuspid regurgitation, and an ejection fraction of 60% managed with intermittent atenolol (Tenormin) dosing, and how can these episodes be differentiated from ventricular tachycardia, atrial flutter, or atrial fibrillation?
