Diagnosis and management of supraventricular and ventricular tachyarrhythmias: Narrow complex tachycardia & wide complex tachycardia

…system (which is slow). However, WCTs may be supraventricular, if the tachycardia is accompanied by one of the following conditions: bundle branch block, aberrant v

🟠 Brugada's algorithm for diagnosing ventricular tachycardia (VT)

Info Brugada's algorithm is the most used algorithm for distinguishing ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with wide QRS complex. The algorithm entails…

Pacemaker-mediated tachycardia (PMT): ECG and management

…ECG Pacemaker mediated tachycardia (PMT) Pacemaker mediated tachycardia may arise if the pacemaker records a rapid atrial rate (e.g. during a supraventricular tachycardia) and…

Atrioventricular nodal reentry tachycardia (AVNRT): ECG features & management

…Supraventricular Tachyarrhythmia (PSVT) The arrhythmias AVNRT, AVRT (Pre excitation, Wolff Parkinson White syndrome) and ectopic atrial tachycardia have traditionally been referred to as paroxysmal supraventricular…

Sinus tachycardia & Inappropriate sinus tachycardia

…Finding the P wave is a requirement for establishing a diagnosis of sinus tachycardia. On the contrary to many paroxysmal supraventricular tachyarrhythmias (e.g AVNRT…

Tachycardia induced cardiomyopathy

…ventricular dysfunction among patients with atrial fibrillation and other supraventricular tachyarrhythmias. Moreover, ventricular tachyarrhythmias (including recurrent episodes of ventricular tachycardia) can also cause this cardiomyopathy…

Sudden cardiac arrest: Case 4
