2024年10月8日 · Ventricular Tachycardia (VT) is a broad complex tachycardia originating from the ventricles. There are several different forms of VT — the most common is monomorphic VT, which originates from a single focus within the ventricles. Monomorphic VT can be difficult to differentiate from other causes of broad complex tachycardia.

Regardless of etiology and ECG, ventricular tachycardia is always a potentially life-threatening arrhythmia that requires immediate attention. The ventricular rate is typically very high (100–250 beats per minute) and cardiac output is affected (i.e reduced) in virtually all cases.

In this review, we discuss the definition of VT, review features of wide-complex tachycardia (WCT) on ECG that might be helpful in diagnosing VT, discuss the different substrates in which VT can occur and offer brief comments on management considerations for patients found to have VT.

Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte imbalance, or a heart attack. [2][3] Diagnosis is by an electrocardiogram (ECG) showing a rate of greater than 120 beats per minute and …

2023年7月30日 · Explain the pathophysiologic basis of ventricular tachycardia. Summarize the differential diagnoses of ventricular tachycardia. Describe the evaluation and management of patients presenting with ventricular tachycardia.

2024年3月6日 · 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.

2025年3月17日 · Simple guide to reading and reporting an EKG step by step. Calculate the heart axis by entering the QRS amplitude in I and III. Calculates the QTc interval by entering QT interval and HR

2013年8月25日 · Ventricular tachycardia is defined as a sequence of three or more ventricular beats. The frequency must by higher than 100 bpm, mostly it is 110-250 bpm. Ventricular tachycardias often origin around old scar tissue in the heart, e.g. after myocardial infarction. Also electrolyte disturbances and ischemia can cause ventricular tachycardias.

Ventricular tachycardia, also called V-tach, is a rhythm that can occur for a short duration and quit or be sustained. If there is a “run of v-tach”, hence it happens for a short duration, you may see a bunch of premature ventricular contractions (PVCs) …

2022年11月10日 · Ventricular tachycardia (VT) is a rapid heartbeat over 100 bpm that originates in the ventricles. The EKG will show three or more irregular heartbeats in a row. Ventricular tachycardia can be classified by type. Several types of VT, including Monomorphic, Polymorphic and Torsade de Pointes are available for review on this website.
