35 years old man with recurrent palpitations, underwent EPS. Two tracings are shown below.

What is the most likely diagnosis?

A woman aged 30, with a known history of dilated cardiomyopathy (left ventricular ejection fraction, LVEF, at 15%), reported experiencing palpitations. Subsequently, three electrocardiograms (ECGs) were conducted and are presented below:

What types of arrhythmias are currently evident?

You are visiting a patient with a dual chamber ICD. Tracing of arrhythmia event is shown.

What is the rhythm and what is the result of therapy?

A 17-year-old girl with palpitations underwent EPS, Two tracings of basic ECG and arrhythmia are shown.

What is the etiology of arrhythmia?

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

Which one is not present in the tracing?

An 82-year-old man with a history of TAVR and PPM-DR insertion due to transient AV Block after TAVR has presented for device analysis with this ECG without any symptoms.

What's your interpretation?

This EKG was observed in a patient with myocardial infarction,

Which of the following statements about the arrhythmia shown in this EKG, observed in the setting of an acute myocardial infarction, is NOT correct?

A 52 y/o lady was admitted to hospital 3 days ago. She received thrombolytic 3 days ago based on initial diagnosis of inferior STEMI .After 3 days, chest pain recurred again, and you called for evaluation of the chest pain.

ECG of day 1,2 & 3 are shown:

Based on most likely diagnosis, What is your recommendation?

45-year-old patient with Frequent PVC (30%) with LVEF=40%, underwent EPS ablation, below you can find Fleuoro shot of the ablation procedure :

Name the LOCATION of each catheter.

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 middle-aged lady underwent EPS with 3D mapping, below you can see the 3D mapping of her arrhythmia :

Based on the 3D mapping, what is the possible arrhythmia?

A 75 y/o lady underwent coronary angiography. she had a history of pacemaker implantation 10 years ago. A shot of her angiography is shown:

Can you guess the kind of pacemaker lead?

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?

The ECG is shown below.

Which statement is NOT correct?

According to video of his catheterization ,can you name the anatomic location marked with *?

A 29 years old man with Tachycardia and low LVEF(25%) underwent EPS and ablation, Surface ECG and EP tracing are shown.

What is probable etiology of cardiomyopathy?

A 55 years old male, with a history of slow pathway ablation 2 years ago, Presented with palpitation most often.

Here you can find his ECG.

Which statment is wrong?

A 40 y/o lady with history of valve surgery is admitted to hospital because of left hemiparesis, she only took warfarin as her medication & her last INR was about 2.2. Echocardiography is shown.

According to the echocardiography, what is your plan for patient ?

A 78 y/o woman came to ED complaining of acute onset of retrosternal chest pain, she was anxious and suffer from severe chest pain. In her past medical history she only had a history of hypertension.at admission to hospital her vital signs were as follow:

BP=160/60  HR=110 RR=22 O2sat in room air=96%

an ECG &bed side echocardiography was done immediately

According to ECG &echocardiography what is your next appropriate step?
