| cardiac arrhythmia | 2.04 | Put simply, cardiac arrhythmia is an irregular heartbeat. | ||
| ventricular arrhythmia | 0.53 | Electrophysiological studies with premature ventricular stimulation generally do not induce ventricular arrhythmias. | ||
| fatal arrhythmia | 0.33 | Scarring, in turn, can lead to potentially fatal arrhythmias. | ||
| life-threatening arrhythmia | 0.26 | Our testing showed no evidence of cardiomyopathy or abnormal life-threatening arrhythmias. |
