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 67-year-old man with a history of frequent palpitations underwent EPS. Below you can find two tracings.

Which statement is WRONG?

A young girl with palpitations underwent EPS, below you can find the tracing of arrhythmia.

which kind of arrhythmia is NOT probable?

50 y/o woman with history of dyspnea on exertion underwent catheterization.

According to video of her catheterization & your presumptive diagnosis for her procedure can you guess which chamber is enlarged?

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 35 y/o lady underwent echocardiography for evaluation of palpitation & Dyspnea on exertion.

What is the most likely diagnosis?

A young lady with a history of frequent palpitations and a prior failed ablation presented for an electrophysiology (EP) study. The ECG during the induced arrhythmia and EP tracing during incremental atrial pacing are shown below.

What statement is WRONG about this case?

Here is a video of a patient in the ICU. The cardiology resident in charge transiently turned off the patient's temporary pacemaker, which caused the patient to go into asystole.

How can this be?

A 63 y/o lady with LVEF=40% and Mild CAD, All ECG tracing showed irregular arrhythmia, three are shown:

What is the rhythm in this lady with tachycardia induced cardiomyopathy? 

Below you can find the sparkle mapping of a case of unsuccessful CCW flutter ablation.

what is the wrong statement? 

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

Which statement is true about the patient?

A young man experiencing palpitations underwent Electrophysiological Study (EPS), revealing the presence of two distinct arrhythmias, as illustrated below:

Which potential diagnosis is considered LESS likely?

A 51-year-old diabetic woman presented with a complaint of chest pain.Based on the ECG coronary angiogram performed.

Based on the ECG and Coronary angiogram,what is the next step?

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 49-year-old man with a history of hypertension and smoking presented to the emergency department complaining of chest pain that started approximately 8 hours ago. His vital signs were stable. ECG is shown below.

Which statement is true?

A 72-year-old woman with episodic palpitations and a history of unsuccessful ablation two years ago was referred for further evaluation. Below is the episode of arrhythmia induced during the EPS (speed: 50 mm/sec).

 Which statement is correct?

A 57-year-old gentleman with a history of NICMP ( EF:20%) underwent ICD implantation three years ago due to episodes of VT and came to our ED with a chief complaint of multiple episodes of ICD Shock.

Below are four shots of his arrhythmia episode:

What is the diagnosis?

Case: Middle-aged lady with palpitations and previous failed ablation at another center. ECGs below. (rest and tachycardia)

What is the most probable diagnosis?

35 y/o man underwent echocardiography for evaluation of nocturnal chest pain. Echocardiography is shown:

Based on the echocardiography, which one is NOT seen in this patient?

A 54-year-old lady came with traumatic syncope. Echocardiogram was normal, SPECT showed no ischemia.ECG Holter monitoring is shown below.

what are the Diagnosis and plan?
