A 71 years old man underwent Ablation for ischemic VT. An EP trace shown below.

Regarding EP tracing which statement is TRUE?

A middle-aged man with a history of frequent admissions due to tachyarrhythmia and two unsuccessful ablation sessions. ECG and 3D mapping from an electrophysiology study (EPS) are shown:

Based on ECG and 3D mapping what is Wrong about this case?

A 56 years old male patient with palpitations and frequent PVCs on surface ECG with PVCs burden of 40% on Holter monitoring , referred for ablation. Below you can find the  surface electrocardiogram.

Based on the surface ECG , what is the most possible localization for PVCs.

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

Which statement is TRUE in this patient?

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

What statement is False?

a 65-year-old lady known case of CHF, Severe MR, Severe TR, and cardiac cirrhosis, with a history of PPM implantation 1 year ago due to episodes of transient CHB came to the ER complaining of palpitation 2 days ago.

Her ECG is shown below 

which diagnosis is less possible for this ECG?

A 35 years old man, presented by recurrent palpitations. Below you can see two traces from 24 ECG Holter monitoring and also a trace during Electrophysiology study.

Regarding these traces, which diagnosis is less likely?

A 21-year-old man suffered a cardiac arrest during physical activity. Cardiopulmonary resuscitation (CPR) was performed for a duration of twenty minutes, and the patient was subsequently transported to the hospital. According to the EMS personnel, the patient had a VT rhythm during cardiac resuscitation, as indicated by the electrocardiogram and echocardiography.

 Which option is incorrect?

A young man with frequent PVC. Below are 3 signals from RVOT, Distal CS, and RCC. 

Which signal do you think is the success signal?

A 57 y/o woman underwent coronary evaluation because exertional chest pain started one year ago.

coronary angiography is shown:

What is your most likely diagnosis?

A 55 years old lady underwent EPS and Ablation, Two EP Tracing are shown below:

What is the best explanation for this tracings?

A 55 years old man underwent eventful CABG 2 days ago. His post op BP was low and needed inotrope and mechanical support. He complained from abdominal pain and dyspnea. Post-op CXR is as follows

What is most important abnormality in CXR? 

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 40 y/o man with a history of hybrid TEVAR operation underwent CT angiography for routine follow up:

CT angiography is shown:

In CT angiography there is an incidental congenital heart defect, can you guess what defect is shown?

Below is the 12-lead ECG of a patient who underwent EPS. Prior to this tracing, we were attempting to capture the "His" signal."

Which statement is wrong?

A middle aged lady,came to our clinic with chief complaint of multiple episodes of palpitation.
here are the EP tracings.

Which arrhythmia is the least possible diagnosis?

A 43 years old gentleman with no remarkable past medical history, presented to the Emergency department with progressive weakness from 7 days ago.
He didn’t recall any pain or any other symptoms.

During first evaluations , his SBP was 250mmHg and his serum creatinine was 7 mg/dl. Based on his Chest X-ray, we performed echocardiography and CT angiography.

Below you can find CXR , CTA and echocardiogram.

What is your plan?

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

What is the diagnosis?

A 68 years old lady, with history of single chamber implantation years ago, underwent CABG. Post-op ECG is shown.

What is your diagnosis? What is your next plan?

A middle-aged lady with a history of dual chamber pacemaker implantation 10 years ago, came to the emergency department, with a temporary pacemaker implanted, ECG after that is shown:

What is the best explanation for the ECG?
