Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?

Dr. Smith's ECG Blog

male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Bedside ultrasound showed volume depletion and no pulmonary edema.

What happens when you give adenosine to a patient with this rhythm?

Dr. Smith's ECG Blog

Here is his 12-lead ECG: The computer reads supraventricular tachycardia. It is atrial flutter with 2:1 conduction. There are clear flutter waves in lead II across the bottom. Adenosine simply blocks the AV node so that there is no QRS to hide the flutter waves, and they become obvious. What is it?

Boston Scientific Initiates AVANT GUARD Clinical Trial to Evaluate FARAPULSE Pulsed Field Ablation System as First-Line Treatment for Persistent Atrial Fibrillation

DAIC

Patients in the study will be randomized to undergo pulmonary vein isolation (PVI) and left atrial posterior wall ablation using the FARAPULSE PFA System, or receive AAD treatment, and followed for three years. The randomized AVANT GUARD trial will enroll more than 500 patients diagnosed with persistent AF at up to 75 sites globally.

Atrial dilatation in Atrial fibrillation : A query with multiple twists!

Dr. S. Venkatesan MD

Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It In all probability, this dilation is a form of atrial tachycardia and atrial cardiomyopathy. Pulmonary veins have been the primary target for ablation for many years, yet the success rates remain inconsistent.

Too fast, too furious

Heart BMJ

She was noted to be in heart failure, with hypotension and tachycardia. Echocardiography demonstrated severe calcific mitral stenosis with pulmonary hypertension. She reverted to normal sinus rhythm with features of left atrial enlargement, a heart rate of 60/min and a prolonged corrected QT interval (474 ms) ( figure 1B ).

A Middle-Aged Man with Chest pain, Hypotension and Tachycardia

Dr. Smith's ECG Blog

There is a narrow complex tachycardia at a rate of 130. ECGs: there is a regular narrow complex tachycardia still at a rate of exactly 130, with no P-waves and also no change since the prehospital ECG. Leads II and aVF appear to have flutter waves. I diagnosed atrial flutter with 2:1 conduction. Is is sinus?

Empirical superior vena cava electrical isolation guided by quantitative ablation index improves outcomes of radiofrequency catheter ablation for paroxysmal atrial fibrillation

Open Heart

Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups.
