Learn how to diagnose ventricular tachycardia from supraventricular tachycardia with wide QRS complex on EKG. See the morphological criteria, Brugada algorithm and Vereckei algorithm with examples and references.
This article is a guide for interpreting abnormal Ventricular Tachycardia EKGs, including qualifying criteria and a sample EKG rhythnm strip. 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 ...
Ventricular tachycardia of short duration or slow rate may be asymptomatic. Sustained VT is almost always symptomatic, causing palpitations, symptoms of hemodynamic compromise, or sudden cardiac death.
Learn how to differentiate ventricular tachycardia (VT) from supraventricular tachycardia with aberrancy (SVT) using the CRAM mnemonic and ECG examples. VT is a potentially life-threatening arrhythmia that requires urgent treatment.
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.
Characteristics and Criteria of Ventricular Tachycardia (V-tach) This rhythm is occurring because there is an abnormal electrical signal in the ventricles causing the ventricles to beat at a very fast rate. Ventricular tachycardia, also called V-tach, is a rhythm that can occur for a short duration and quit or be sustained.
Electrocardiographic diagnosis of ventricular tachycardia (VT). (a) 12-lead electrogram (ECG) showing wide complex tachycardia with right bundle branch block configuration. Diagnosis is made from the regular P-waves, which are dissociated with QRS complexes and indicated by red arrows. (b) Electrograms from an implantable cardiac device (ICD; in this case, a biventricular ICD). Top line (blue ...
Learn how to identify ventricular tachycardia (VT) on ECG, differentiate it from wide complex SVT, and treat it with ACLS protocols. Find out the causes, mechanisms, and complications of VT and its clinical presentation.
Ventricular tachycardia (VT) is a crucial diagnosis to not miss. Especially for an ER physician. If the patient is crashing, a wide complex tachycardia gets treated like VT and the patient gets a healthy dose of electricity. Those cases are easy. What about cases where there is more time to consider other possibilities? What if you have a stable patient with a wide complex tachycardia? This ...
Learn how to recognize, classify, and localize monomorphic ventricular tachycardia (VT) and related rhythms on the ECG. Find out the causes, mechanisms, and treatments of VT and how to differentiate it from SVT with aberrancy.
Ventricular Tachycardia (VT) - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the Merck Manuals - Medical Professional Version.
Learn how to identify and treat these serious cardiac arrhythmias that can cause death. See the differences, causes, risk factors, and ECG patterns of ventricular tachycardia and ventricular fibrillation.
Ventricular tachycardia is a type of heart rhythm problem (arrhythmia) that starts in the heart’s bottom chamber. It typically occurs in people who have had a heart attack or other damage to their heart muscle.
This article is a guide for the ECG interpretation of Ventricular Tachycardia, including a sample ECG strip. This is our online abnormal ECG interpretation cheat sheet!
No P wave, wide and bizarre QRS. Ventricular Tachycardia occurs when the rate exceeds 100 bpm. Approximately 50% of patients become unconscious at the onset of ventricular tachycardia. Although patients in V Tach may be treated with a defibrillator, not all patients in Ventricular Tachycardia require this level of treatment.
