A 55 years old man with HOCM, referred for evaluation of 48h ECG Holter monitoring

What is the rhythm?

A 25-year-old patient came to our clinic with the chief complaint of palpitation, based on his surface ECG, we scheduled him for EPS.

According to his surface ECG and EP tracing, which statement is not true?

An 80 year old asymptomatic lady came with below ECG:

What is your diagnosis?

A middle-aged patient with history of AVR, symptomatic PVC (30%) unresponsive to beta-blockers and Sotalol. ECG is shown: 

What is your plan? 

A 60 y/o man with a history of PCI on LCX comes to ED complaining of acute chest pain and dizziness.

the ECG is shown:

what is your diagnosis and proposed treatment strategy?

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 dual chamber pacemaker implanted for a patient. One hour after implantation, you called by a nurse for "strange rhythm". Two shots of Pacemaker analysis are given.

What is the problem?

Below you can find the angiogram of a patient.

What would you not expect to find in an echocardiogram?

A 21-year-old man with dyspnea on exertion (DOE) (FC II) presented to the emergency department. An echocardiography video is provided below for review.

Based on the echocardiography images, which option is incorrect?

A 78 year old lady with history of diabetes mellitus, hypertension, heart failure (ejection fraction about 30 percent), COPD and no documented history of arrhythmia has been admitted due to combined COPD exacerbation and decompensated heart failure. baseline ECG is shown below. after 3 days of admission she experienced palpitation and ECG during palpitation is also shown.

What is the most correct diagnosis and management?

A 45 y/o lady underwent EPS for evaluation of wide complex tachycardia.

EP tracing is shown:

What is the best explanation for this tracing?

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 31 years old man was admitted to hospital with Non-STEMI. He had no known coronary artery disease (CAD) risk factors, but had a history of prolonged unexplained febrile disease when he was five years old. Coronary angiography performed. Two shots are given below.

What is the most likely etiology?

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

What is the most probable diagnosis?

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 72-year-old man with a known history of Parkinson’s disease presented to our ED with a chief complaint of palpitations. Below is the intracardiac EGM from his EP study.

What is the diagnosis, and what is the most likely mechanism behind the variation in Tachycardia Cycle Length (TCL)?

A 51-year-old woman with a history of hypertension and thyroid surgery eight years ago was brought to the emergency department due to severe generalized weakness that began a few hours prior. She was awake but uncooperative in providing a detailed history. Her blood pressure was recorded at 225/146 mmHg. An ECG was performed (which is shown below).

Which management strategy is most likely to benefit the patient?

A 52-year-old man with a past medical history of hypertension presents with dyspnea. Myocardial perfusion imaging demonstrates reversible ischemia in the anterior wall territory. Elective coronary angiography sequence is displayed below.

Based on the most likely diagnosis, which of the following options is incorrect?

A 45 years old women came to office with mildly positive MPI scan. She was worried about the results. She was hypertensive with family history of premature coronary artery disease. Cardiologist decided to perform coronary angiogram. 
Angiogram is shown:

What is the diagnosis and the appropriate treatment strategy? 

You are on an on-call duty, emergency department nurse sent you the following ECG.

What is your next appropriate step in management of the patient?
