Mar 6, 2024 · Tests are done to check the heart and confirm a diagnosis of ventricular tachycardia, also called V-tach or VT. Test results also can help determine if another health problem is causing V-tach. Electrocardiogram (ECG or EKG). This is the most common test to diagnose tachycardia. An ECG shows how the heart is beating.
Ventricular tachycardia can be caused by many different things. The most common cause is ischemic heart disease (heart disease that causes the heart to not get enough oxygen). Ventricular tachycardia can also be caused by other problems, like: Cardiomyopathies (diseases that affect the heart muscle)
Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia. Ventricular arrhythmias include ventricular fibrillation and ventricular tachycardia. Bradyarrhythmias are due to sinus node dysfunction or atrioventricular conduction disturbances.
Jun 12, 2022 · Ventricular tachycardia is an abnormal heart rhythm that happens when you have abnormal electrical signals in your heart’s lower chambers (ventricles). These keep normal heartbeat signals from getting through and make your heart beat so fast that it can’t pump enough blood to your body.
Dec 15, 2023 · Ventricular tachycardia. This irregular heart rhythm starts in the lower heart chambers, called the ventricles. The fast heart rate doesn't let the ventricles fill and squeeze to pump enough blood to the body. Episodes may be brief and last only a couple of seconds without causing harm.
Jul 30, 2023 · Ventricular tachycardia (VT) is a wide complex tachycardia, defined as three or more consecutive beats at a rate of more than 100 per minute, arising from the ventricle. Ventricular tachycardia is a potentially life-threatening arrhythmia, and it is responsible for the majority of sudden cardiac deaths in the United States.
Ventricular tachycardia is 3 consecutive ventricular beats at a rate 120 beats/minute. Symptoms depend on duration and vary from none to palpitations to hemodynamic collapse and death. Diagnosis is by electrocardiography. Treatment of more than brief episodes is with cardioversion or antiarrhythmics, depending on symptoms.
