Electrical injury is a serious public health problem. Heart is one of the most frequently affected organs. Electrical injury can cause life-threatening cardiac complications such as asystole, ventricular fibrillation, and myocardial rupture. In this case report, we present a 20-yr-old male patient with sick sinus syndrome that developed years after electrical injury.
Anomalous origin of the right coronary artery arising from the left anterior descending artery (LAD) is a very rare coronary anomaly. It has previously been reported in only six adult cases. In this report, we present a patient with an anomalous origin of the right coronary artery from the LAD. The patient had anginal symptoms with exercise. Myocardial perfusion imaging with thallium-201 revealed a reversible inferior perfusion defect. We suggest that this could cause myocardial ischemia.
We studied the seasonal variability of P dispersion in 523 healthy male patients, aged 22 +/- 4 years (range, 20-26). Four seasonal 12-lead resting electrocardiograms were recorded at 2 mV/cm standardization and at 50 mm/s paper speed at intervals of three months. Electrocardiograms were recorded between the hours 10 to 12 AM. The difference between the maximum P-wave duration and minimum P-wave duration was calculated and defined as "P dispersion." There was a significant seasonal variation in the maximum P-wave duration (P = .001) and P dispersion (P = .001), with the longest maximum P-wave duration (121 +/- 16 ms) and P dispersion (41 +/- 7 ms) observed in winter and the shortest maximum P-wave duration (106 +/- 15 ms) and P dispersion (24 +/- 8 ms) observed in summer. The minimum P-wave duration did not show any significant seasonal variation. In conclusion, there exists a significant seasonal variation in the maximum P-wave duration and P dispersion in healthy patients. Seasonal variation of P dispersion resulted from the significant variation of maximum P-wave duration.
Ventricular fibrillation in a patient with ventricular preexcitation is usually due to atrial fibrillation with an extremely rapid ventricular rate from which it degenerates. We present a case with Wolff-Parkinson-White syndrome and coexistent idiopathic ventricular fibrillation. The patient, a 23-year-old male, had had a cardiac arrest four years earlier. In electrophysiological study, the accessory pathway was located in the left posteroseptal region and successfully eliminated with radiofrequency catheter ablation. After the ablation procedure, ventricular fibrillation was induced with programmed ventricular stimulation. A dual chamber implantable cardioverter defibrillator was implanted in the patient.

Persistent left superior vena cava is an unusual congenital anomaly that can coexist with accessory atrioventricular pathways. This anomaly can cause difficulty in mapping because of the dilated coronary sinus. This study describes a successful catheter ablation in a young male with persistent left superior vena cava and Wolff-Parkinson-White Syndrome as a result of a left lateral accessory pathway.
