What statement is WRONG about this tachycardia episode?

A 54 years old man with a history of STEMI and primary PCI months ago presented with palpitations, Rest ECG and the arrhythmia ECG are shown : 

What is the most possible diagnosis?

Below you can find EP tracings of AF cryo-ablation of a young lady with paroxysmal AFib.

Which statement is WRONG about these tracings?

A middle aged patient underwent EPS and Ablation for palpitation, ECG of arrhythmia before and after Adenosine are given with a trace of EP. 

What is the most possible diagnosis?

A 35 y/o lady came to your clinic for routine checkup. She claimed that she had a congenital heart disease which was corrected many years ago.

according to CXR ,what is your assumption for her past congenital disease?

A 29 years old man with Tachycardia and low LVEF(25%) underwent EPS and ablation, Surface ECG and EP tracing are shown.

What is probable etiology of cardiomyopathy?

A 32 y/o young man with congenital heart disease admitted to hospital for surgery. ECG is shown:

What is your best diagnosis according to ECG?

A 24-year-old patient with PVC burden of 33%, low LVEF=20%, ECG and echo are shown.

what is the best strategy for the patient?

A 38-year-old with palpitation.ECG during palpitation is shown:

What is the most probable diagnosis?

A middle-aged patient with palpitation underwent EPS. EP tracings are shown:

According to EP Tracings, what is the diagnosis?

A 50 y/o came to ED complaining of episodes of palpitation, his past medical history is otherwise unremarkable.

what is your most likely diagnosis for the patient?

A 68-year-old woman with the past medical history of aortic valve replacement (AVR), mitral valve replacement (MVR), and septal myectomy (2013), presents to the emergency department. She reports a two-day history of substernal heaviness. The onset of her symptoms coincided with a interpersonal conflict involving her daughter and son-in-law.

Her prior coronary angiography, performed at the time of her valve surgery, was reported as normal.

Based on the most probable diagnosis suggested by the ECG and echocardiography findings, which of the following choices is correct?

A 70-year-old woman experiencing dizziness; below are the ECGs captured over the course of one day.

Which option is NOT as accurate in this scenario?

A middle-aged patient underwent EPS and Ablation for incessant arrhythmia, below you can find 12 lead ECG and EP tracings of the patient.

What is the most probable arrhythmia? 

A 60y/o man with a history of coronary artery disease and heart failure with EF=15% came to ED complaining of palpitation.ECG of tachyarrhythmia and previous ECG in sinus rhythm are shown:

What is your most likely diagnosis?

Below you can find a 12-lead ECG and EP tracing of a middle-aged man with palpitations.

Which one is the most likely diagnosis?

A 34 y/o man came to ED complaining of retrosternal chest pain  which was started 2 hours ago & lasted one hour .He was mentioned an episode of heavy weight lifting the day before. He had no known coronary artery disease risk factor in his past medical history.

two sets of troponin was sent:

1st hs-cTnT=80 ng/L(upper limit<24 ng/l)

2nd hs-cTnT=84 ng/L(upper limit<24 ng/l)

so he was undergone coronary angiography with diagnosis of NSTEMI

what is your most likely diagnosis for this patient?

According to case 641.

 What is the best plan for managing his arrhythmia?

A middle-aged lady with wide complex tachycardia underwent EPS. ECG of Arrhythmia and an EP tracing of high RA pacing are shown below:

What is the most probable diagnosis?

Below you can find 3D mapping and EP signals of a case of VT ablation: 

What statement is wrong in this case?
