Older patients can usually describe the sudden onset of a pounding heartbeat, which is regular and “too rapid to count.” This is typically accompanied by a concomitant change in their tolerance for activity. An irregular rhythm may herald the presence of atrial fibrillation (AF). Occasionally, evidence of disease is discovered on routine electrocardiography (ECG), independent of a concurrent tachydysrhythmia.
