You see the angiogram of a patient.

What kind of pacemaker lead is this?

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

What is the rhythm?

A young man with palpitation underwent EPS. An EP trace is given:

Three beats are marked, explain each of them separately :

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 31 years old woman presented with paroxysmal palpitation.here there is her ECG Holter.

Which statement is NOT correct?

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

What is the diagnosis?

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 middle-aged patient with a history of ICD implantation complained about palpation. The ICD tracing is shown:

which statement is WRONG?

A female patient aged 53 years, with a medical history of aortic valve replacement (AVR), mitral valve replacement (MVR), and tricuspid valve repair (TVr) five years ago, presented at the medical facility without any symptoms but with a prolonged withdrawal from warfarin for several months. The patient was admitted, and heparin therapy was initiated along with a transthoracic Doppler echocardiography (TDI TTE) examination and fluoroscopy. 

Based on the results obtained from the TDI TTE and flouroscopy what do you consider the most appropriate course of action?

An ECG of an elderly man with fever is provided below.

Seeking the optimal explanation for this ECG. What's your take?

A 66 y/o man underwent coronary angiography for evaluation of patients dyspnea.

which statement is true about our patient?

A young woman with an antrospetal accessory pathway (AP) underwent an electrophysiology study (EPS) and ablation. Following the procedure, adenosine was administered to confirm the elimination of the AP pathway. The tracing below was recorded during the adenosine injection

Which statement is NOT correct about this tracing:

Below are the electrophysiological (EP) tracings of a 42-year-old patient presenting with the primary complaint of palpitations:

Which statement is FALSE?

A 56-year-old male was referred for an arrhythmia. Here you can find the 24h ECG Holter.

The patient had no complaint of palpitation.

What is the best diagnosis?

A 70 y/o man came to ED complaining of dyspnea on exertion from long time ago. He claimed that he had a prosthetic valve, no medical record is available. Fluoroscopy is shown.

Can you guess the type & position of prosthetic valve?

Following case 632, the patient underwent EPS and ablation. The tracings are displayed below.

Which statement is not correct?

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

What is the most probable diagnosis?

A 40 y/o man, with no previous PMH came to ED .He was referred by general practitioner for evaluation of AV block, the patient was asymptomatic and received no drugs.

The ECG was done during routine checkup.

What is your diagnosis and management?

A 52 y/o lady with recent dual chamber pacemaker implantation presented by dizziness.

ECG and Chest XRay are shown.

PPM analysis showed Normal RA and RV impedance, Normal Atrial lead sense and pacing, no RV capture.

What is the etiology of device malfunction?

A middle-aged lady had EPS for several episodes of palpitations, An EP trace during RF ablation is shown:

What is inferred from this tracing?
