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

What is the best explanation for this tracings?

Below you can find a "plot diagram" of a patient with an ICD. 

Which statement is WRONG?

An 80 years old lady with tachycardia, both resting ECG and arrhythmia are shown: 

What is the diagnosis?

A 50 y/o man underwent echocardiography for assessment of heart murmur.

What is your most likely diagnosis?

An elderly woman with a history of a dual-chamber permanent pacemaker (PPM) from years ago presented with complaints of dizziness. The accompanying ECG and device tracing are provided for further evaluation.

Given the device tracing, which plan would be more suitable?

55 years old woman with history of episodic atrial fibrillation and severe mitral regurgitation who was on warfarin from 1 year ago, underwent Mitral Valve Replacement (MVR) 4 days ago. She was transferred to post-ICU ward in sinus rhythm but the palpitation suddenly begun (below ECG). 

Her vital signs were as follows: BP 95/60, No fever, Acceptable Respiratory Rate, Heart Rate 130.  

Bed-side Echocardiography showed moderate Left Ventricle (LV) dysfunction (EF 35-40%), mild Right Ventricle (RV) dysfunction, Good MV bileaflet motion and dilated Left atrium (LA).

What is your diagnosis and reasonable therapeutic approach? 

A young lady with palpitations. ECG of the arrhythmia is presented below.

Which diagnosis is NOT probable?

A 23-year-old woman experiencing palpitations has been referred for further evaluation. The 12-lead ECG is presented below.

Which statement is TRUE? 

A electrocardiogram (ECG) of a young boy is shown below:

What is an appropriate statement to describe premature ventricular contractions (PVCs)?

You see the angiogram of a patient.

What kind of pacemaker lead is this?

Below you can find the Activation map and propagation map of a case with narrow complex tachycardia.

Based on these movies, which statement is TRUE?

Below you can find 3D mapping and EP signals of a case of VT ablation: 

What statement is wrong in this case?

A 65 y/o man with history of MVR 2 years ago come to ED complaining of new onset dyspnea from 3 days ago.

Which statement is TRUE about the patient?

A young woman underwent an electrophysiology (EP) study. Interpret the tracing below.

What is WRONG about this tracing:

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 39-year-old man was brought to the emergency department by ambulance with presentation of sudden and complete LOC.

Basic life support was perform before arrival at the hospital. Cardiac monitoring showed ventricular fibrilation and patient recieved defibrilation then pulse became detectable. The first ECG which was taken 3minutes after DC shock is shown below.

Which of the statments presented here is true about this patient?

55 y/o lady with recurrent palpitations underwent EP study. Two traces of EPS are shown.

What is the most likely arrythmia?

A 62 y/o female pateint was presented with progressive dyspnea from 2 months ago and massive right sided pleural effusion. 

In her past medical history she had a pathologic L1 fracture 6 months ago and due to normochromic normocytic anemia, bone marrow biopsy was performed 10 days ago.

Bellow you can find ECG and echocardiogram.

which one has proven benefit in this setting ?

A middle-aged lady came with palpitations, three ECGs are shown below:

What is your diagnosis?

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

Which statement is NOT correct?
