A middle-aged man with a history of accessory pathway ablation came to our clinic with chief complaint of recurrent palpitations.
(ECG:1-2)
He was scheduled for EP study, and the accessory pathway was successfully ablated.
The day after, he was complaining of pleuritic chest pain.(ECG :3)

Bedside echo revealed mild pericardial effusion.

which statement is not correct?

A young lady underwent EPS for palpitation, during ventricular pacing this arrhythmia happened.

What happened?

A 58 years old man with several episodes of syncope once in supine position. Baseline ECG showed RBBB and LAHB (bifascicular block). LVEF=55%, EPS done. EP tracing is shown:

What is the tracing interpretation and next plan?

A middle-aged man underwent a coronary angiogram, below you can find angiography and concomitant 12 lead ECG:

What is your diagnosis?

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

What statement is wrong in this case?

A 72-year-old male with a history of CABG 10 years ago and PPM-DR implantation last year due to CHB presented to the ER with a chief complaint of fatigue and dizziness persisting for the past month. Bedside echocardiography revealed an ejection fraction (EF) of 30-35%, moderate mitral regurgitation (MR), and no pericardial effusion.

Based on the ECG findings, what underlying condition or situation could be LESS responsible for these symptoms?

Below you can find the 3D mapping ablation of case 564. 

What statement is False?

A 65 years old man underwent a procedure,  ECG before and after the procedure are given:

Regarding ECG before and after, guess what procedure done for the patient.

A young lady with no structural heart disease underwent EPS for wide complex tachycardia, two EP tracings are shown below:

What is the diagnosis?

A 40-year-old woman complained of heart palpitations;

Based on echocardiography, which option is wrong?

A middle-aged lady with frequent palpitations, EP tracings are shown below.

What is the most probable diagnosis?

A 67 years old male with hx of CABG 10 years ago and PTE last year (since then he is on anticoagulant therapy), presented to ER complaining of ACP. ECG is shown below;

What is the next step?

A middle-aged patient underwent EPS ablation for flutter. See the procedure summary below :

Which statement is wrong?

• An 85 y/o woman was brought to ED by her children. She suffered from dementia so she could not explain her symptoms but her children claimed that their mother has experienced a syncopal attack a few hours before. She did not take any beta-blocker or calcium channel blocker in her drug history.

According to her ECG what is your next step for her management?

70 y/o man with history of coronary artery disease underwent echocardiography . TTE was shown:

Which one of the following was NOT seen on this echocardiography?

A 39-year-old lady with frequent palpitation, you can find ECG and EP tracings. 

What is the most probable diagnosis?

An 82-year-old lady came to the ER with the chief complaint of palpitation, she denied any complaints of dyspnea and chest pain, and her past medical history was remarkable for Dual chamber pacemaker implantation 6 months ago due to complete AV block.

what is the best next step ?

A 40 y/o woman came to your clinic for evaluation of chest pain. She claimed that she suffer from exertional chest pain for many years.

what is your diagnosis?

A 79-year-old man with palpitation underwent EPS, below you can find EP tracing.

What is your diagnosis base on EP tracing:

A 35-year-old man was referred for an electrophysiology study due to multiple episodes of PSVTs. During EPS arrhythmia was easily induced, which you can find below as tracing A. After localizing the best signal, with RF application the retrograde activation of arrhythmia changed (tracing B).

According to tracing A and B, which statement is correct?
