According to video of his catheterization ,can you name the anatomic location marked with *?

Below you can find the ECG of arrhythmia and CS venogram during RF ablation.

Where is the ablation catheter and what was the target of ablation?

A 30-year-old woman with a history of ASD repair was a candidate for EPS and ablation. Below, you can find the EP tracings

Which statment is wrong ?

ECG is shown:

According to ECG, which one of the following could not explain the ECG changes?

What is the arrhythmia?

The patient in case 379, underwent EPS, the epicardial approach was needed.

Based on ECG and Precision mapping images, why we had to perform a subxiphoid epicardial approach?

A 39-year-old woman is experiencing paroxysmal palpitations. Below are the electrophysiological (EP) tracings.

What is the most probable diagnosis?

Sad day at the emergency department unit!

18 y/o girl came to ED complaining of worsening dyspnea since two weeks ago. She claimed that she could not sleep at all because of dyspnea. In her medical records, according to chronic cough, she was recently underwent a biopsy of the lymph node in her mediastinum, and the results showed lymphoproliferative disorder.

Her vital sign: HR=140 beat/min  BP=90/60   O2saturation=93 %    RR=30

An ECG & echocardiography was done immediately.

which statement is NOT true about the patient?

A young lady with palpitation underwent EPS and ablation. Surface resting ECG is shown.

What is the most probable diagnosis of the patient's arrhythmia?
