A Young man with recurrent palpitations underwent EP and ablation, Below you will find a tracing during RF ablation.

What is shown by tracing?

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 middle-aged patient came for Device analysis, below you can find the screenshot of analysis.

Which statement is NOT true?

54 years old woman was referred for electrophysiology study, due to multiple episodes of sudden palpitations. The arrhythmia was induced via atrial burst pacing.

Below you can find tracings of arrhythmia.

Which diagnosis is least possible?

A 52 y/o man underwent echocardiography for evaluation of dyspnea on exertion .

Based on echocardiography could you guess the mechanism of severe MR?

A 35 years old asymptomatic man was referred for evaluation of ECG, two ECGs are shown, the first one was captured during covid when he was febrile the other is today's ECG.

What are you going to do?

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 40-year-old man complained of shortness of breath and orthopnea during the last week. He had no usual cardiovascular risk factors, no history of medication, supplement, or drug use, and no history of recent viral infection.

The patient's appearance is significantly different from other family members (e.g. he is taller than his brothers.)

In the electrocardiogram, sinus tachycardia was seen.

In the echocardiography, EF=20% was reported and there was no evidence of LVH.

In the coronary angiography, there were no coronary lesions.

Based on his physical appearance, Which finding of the patient seems incorrect?

A 62 year-old-man was referred with a history of palpitations, LVEF=40%, and mild coronary artery disease. Two sets of ECG are shown.

Which of the option is NOT evident in these ECGs?

A 61-year-old man with a history of CABG is a candidate for elective cholecystectomy. He is relatively asymptomatic, and the 12-lead ECG is provided below.

What is your plan?

Below you can find the EP tracing of a patient with narrow complex tachycardia.

Which one is not present in the tracing?

The image below shows  fluoroscopic views (LAO & RAO) of mitral annulus accessory pathway ablation via retrograde trans-aortic approach in three patients: A, B, and C

Which one is related to the Posteroseptal accessory pathway ablation?

A 17-year-old male with no significant past medical history presented with the chief complaint of palpitations. His surface electrocardiogram (ECG) and electrophysiological study (EPS) are illustrated below:

Choose correct answers about his arrhythmia?  

27 years old girl underwent EPS for palpitation. An EP tracing during EPS is shown.

Which statement is TRUE about this tracing?

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 52-year-old woman with episodes of syncope underwent a Brugada challenge test, in which she was given 400 mg of oral flecainide. The results of the test are shown below.

What statement is wrong?

A 60-year-old male patient with a history of hypertension, hyperlipidemia, and smoking was admitted to the hospital two days ago, with a diagnosis of anterior MI, and underwent primary percutaneous coronary intervention (PCI) to his left anterior descending artery (LAD).

Two days after the PCI, the patient developed symptoms of heart failure, including dyspnea, cough, and fatigue. His blood pressure was 90/60 mmHg, and his heart rate was 110 beats per minute. Physical examination revealed crackles in both lung fields and holosystolic murmur.  His ECG and echocardiography are shown below.

Based on ECG and echocardiography, which option is more likely to be diagnosed?

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?

An 20-year-old woman experienced syncope at home and was transported to the hospital by EMS. Upon arrival in the ER, her GCS score was 10, and the emergency physician noted pupil dilation in both eyes. Her medical history revealed no cardiac problems, either personal or familial. The only significant finding in her history was the use of oral contraceptive pills (OCP). This is her ECG. 

What is the next step?

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?
