6 mar 2024 · Ventricular tachycardia is a type of irregular heartbeat, called an arrhythmia. It starts in the lower chambers of the heart, called the ventricles. This condition also may be called V-tach or VT. A healthy heart typically beats about 60 to 100 times a minute at rest.
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
30 lip 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. [1] Ventricular tachycardia is a potentially life-threatening arrhythmia, and it is responsible for the majority of sudden cardiac deaths in the United States. [2]
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.
12 cze 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.
Ventricular tachycardia is most commonly associated with ischemic heart disease or other forms of structural heart disease that are associated with a risk of sudden death. Several groups of patients who are at increased risk of sudden death from VT have been identified and benefit from ICDs.
Definition or Description; Ventricular tachycardia S2.2.2-2: Cardiac arrhythmia of ≥3 consecutive complexes originating in the ventricles at a rate >100 bpm (cycle length: <600 ms). Types of VT: Sustained: VT >30 s or requiring termination due to hemodynamic compromise in <30 s. Nonsustained/unsustained: ≥3 beats, terminating spontaneously.
