For instance, a single premature beat may be perceived as a "palpitation" or "skipped beat.
The extent of the heartbeat disorder can range from a single premature beat (often felt as a "thump" in the chest or palpitation) to a lethal heart rhythm called ventricular fibrillation--a disorganized, rapid (400 to 600 times per minute) heart rhythm originating in the bottom chambers (ventricles) and preventing blood flow to the brain, which causes death in three to five minutes unless reversed.
Comment: Magnesium deficiency can lead to various arrhythmias, including ventricular premature beats, atrial fibrillation, supraventricular tachycardia, torsades de pointes, supraventricular ectopic beats, bigeminal rhythm, and ventricular fibrillation.
24 hours holter electrocardiography revealed heart rate ranging from 49 to 97 beats per minute and ventricular premature beats.
We report a patient who had drug-refractory, repetitive polymorphic VTs after myocardial infarction (MI) which could only be managed by radiofrequency ablation (RF) ablation of triggering ventricular premature beats (VPCs).
