Frequent ventricular tachycardia in duplex or triple rhythm is a serious condition. There are many types of arrhythmias, and frequent ventricular premature beats in duplex or triple rhythm is a serious one because it is highly likely that ventricular tachycardia will occur. Ventricular tachycardia is a malignant arrhythmia, and the patient’s life may be in danger due to impaired pumping of blood from the heart. It is even more dangerous if the patient has underlying heart disease and requires early medical attention. Ventricular tachycardia in duple rhythm means that one normal heartbeat is followed by a single premature beat, while ventricular tachycardia in triple rhythm means that two normal heartbeats are followed by a single premature beat. The patient should undergo an electrocardiogram as soon as possible to determine the nature and location of the premature ventricular beats, and then choose medication or surgery according to the doctor’s advice.
