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

What is shown by tracing?

A young lady with minimal preexcitation underwent EPS, EP tracings are shown below

What is the possible diagnosis?

A 36-year-old woman with a medical history of coronary artery bypass grafting (CABG) performed 2 years ago, insulin-dependent diabetes mellitus (DM), hyperlipidemia, and hypertension presented to the emergency department (ED) with complaints of fever and severe weakness lasting for 2 days. An electrocardiogram (ECG), displayed below, suggests the presence of Brugada syndrome. Additionally, while sitting on a chair in the ED, the patient experienced a syncopal episode. Consequently, the decision was made to admit the patient based on the syncope and ECG findings.

A coronary angiogram conducted 1 year ago revealed triple-vessel disease (3VD) and a patent left internal mammary artery (LIMA) graft on the left anterior descending artery (LAD). The posterior descending artery (PDA) demonstrated a patent saphenous vein graft (SVG), and there was significant diffuse stenosis observed in the SVG on the obtuse marginal (OM) branch, for which medical treatment was planned.

Troponin levels were negative upon presentation and remained so throughout the patient's admission.

Also, the ECG can be seen below.

Among the following measures, which one do you consider unnecessary?

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?

A 40 y/o man came to ED complaining of severe retrosternal chest pain which was started from 3 days ago.

ECG is shown:

According to ECG can you guess the location of occlusion in coronary artery?

A 66 y/o man came to your clinic for evaluation of his chest pain. He described his pain as a NYHA class III exertional chest pain from many years ago.

what is your most persumptive diagnosis for this patient?

A  53 y/o man underwent echocardiography for evaluation of chronic dyspnea on exertion & edema.

Which statement is true about the patient?

A 65 years old male patient, admitted with persistent atrial fibrillation (ECG 1). in Echo he had a reduced EF (ca. 20%), in transesophageal echo we excluded intracardiac thrombus. Then we started with Amiodarone, three days later on telemetric ECG monitoring we saw frequent PVCs (ECG 2). We saw somthing wrong in these 12 lead ECG's (ECG 3 and 4).

What is the most probabe cause of these changings?

A 79 years old patient with frequent palpitations. ECG Holter tracings and EP tracings are shown:

What is the most possible diagnosis?

A 23-year-old man with palpitations and frequent PVCs on surface ECG and Holter monitoring (PVC burden: 41%), referred for ablation. Below you can find ECG and EP tracing (Figs. A and B). 

What is the most likely site of origin of the premature ventricular contractions (PVCs)?

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

What is the best explanation for this tracings?

A middle-aged patient with no structural heart disease came to ED with syncope. ECG is shown.

Based on 12 lead ECG what are your diagnosis and plan?

A 45 y/o lady came to ED complaining of atypical chest pain. According to ECG changes, two sets of troponin were sent, which came negative.

ECG & Coronary angiography were shown:

Which one of the following was not seen in the angiography?

A 60 y/o lady, with complaints of recurrent everyday palpitations, 24h ECG Holter revealed several episodes of tachy arrhythmia, LVEF= 40%. One page of holter shown below:

What is the most probable etiology according to arrythmia behavour in ECG Holter?

A 38-year-old woman with recurrent premature ventricular contractions (PVC), a low left ventricular ejection fraction (LVEF), and a history of unsuccessful radiofrequency ablation (RFA) at another hospital underwent an electrophysiology study (EPS).

Where is the ablation catheter positioned? What are the potential complications?

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 32-year-old male presents to the cardiology clinic with a history of palpitations and syncope. He reports that he has been experiencing these symptoms for the past six months, and they have been increasing in frequency and severity. He denies any chest pain or shortness of breath.

A transthoracic echocardiogram (TTE) reveals mild dilatation of the right ventricle (RV) with reduced RV function and an ejection fraction of 40%. The left ventricle (LV) is normal in size and function.

The EKG is shown.

Based on the diagnosis, which one is correct?

A 43-year-old  gentleman with a known case of Apical HCM underwent 48-h ECG holter monitoring for SCD risk stratification.

Below is one shot from his ECG Holter Monitoring :

Which one is the best next step?

The patient is a case of HOCM , you will see part of ECG Holter monitoring.

What is the rhythm and what is your decision for the patient?

A 38-year-old with palpitation.ECG during palpitation is shown:

What is the most probable diagnosis?
