Witryna22 mar 2024 · Premature ventricular contraction (PVC) is one of the common ventricular arrhythmias, which may cause stroke or sudden cardiac death. Automatic long-term electrocardiogram (ECG) analysis algorithms could provide diagnosis suggestion and even early warning for physicians. However, they are mutually exclusive in terms of … WitrynaVentricular tachycardia in ischemic heart disease. Coronary artery disease (ischemic heart disease) is by far the most common cause of ventricular tachycardia and the mechanism is mostly re-entry. As mentioned earlier in this chapter, re-entry occurs when there is a central block ahead of the depolarizing impulse and the cells surrounding …
