Which statement is WRONG about these tracings?

A beautiful smart young doctor with frequent paroxysmal palpitations, EP tracing is shown below:

What is the diagnosis?

 What is the best plan for managing his arrhythmia?

A 65 years old lady implanted dual chamber pacemaker recently, ECG and Chest X-Ray is shown.

Which statement is TRUE in this patient?

A 64-year-old lady came to your clinic with the chief complaint of palpitation. The 24-hour ECG Holter is shown below:

What's the  accurate diagnosis for the WCT revealed in ECG holter?

A 39-year-old man with history of DCM and reduced LVEF (25%), presented with palpitations and frequent PVC on surface ECG and Holter monitoring (PVC Burden: 40%), referred for ablation. EPS was done by 3D NAVX/Precision mapping guide. Initially, Based on surface ECG which was compatible with LV summit origin, mapping was started within CS, the best earliest signal was found in GCV (-42ms). RF applied on aforementioned area, but PVCs did not disappear. So, mapping was done via retrograde trans-aortic approach. After maintaining safe distance from LM,LCX and LAD by coronary angiography and considering correspondent point from epicardial mapping, the best earliest point was found around ILT area (-44ms). RF applied on aforementioned area and PVCs disappeared immediately.

Four fluoroscopic views and surface ECG are shown.

Which of the fluoroscopic views is in favor of catheter ablation position in the ILT (Inter Leaflet Triangle)?

A 35 years old man with palpitations and low LVEF=40%, ECG and Holter tracings are shown:

What is your diagnosis and treatment plan?

A 60 years old man with sustained arrhythmia and low LVEF (ECG below) underwent EPS and RF ablation, propagation mapping of right atrium and ECG is shown: 

In regard to ECG and propagation mapping of RA, what is the possible arrhythmia?

A 51-year-old man with no known coronary risk factors presented to the emergency department (ED) with a four-day history of chest pain.

Based on the patient’s ECG findings, which of the following is the most appropriate next step?

A middle-aged patient with a history of atrial septal defect (ASD) repair underwent an electrophysiology study (EPS) with Precision. Below, you can find the propagation and sparkle map.

What is the most probable mechanism of arrhythmia? 

22 y/o girl referred to EP clinic with LVEF=30% with global HK and "arrhythmia"

Two ECG is shown.

What is the most likely diagnosis?

Which statement is NOT correct?

A middle-aged gentleman experiencing palpitations has undergone a Holter ECG, revealing frequent atrial tachycardia and a notable prevalence of frequent  PVC (27%). He was on beta-blocker with LVEF=35% Included below are two electrocardiograms (ECGs).

What is your plan?
