A 66-year-old woman presented to our emergency department with acute onset of chest pain and dyspnea that had started 6 h earlier.  BP = 120/70 mm Hg, HR=113 beats/min, RR 26/min.  O2 saturation 92% in room air. She had a coronary angiography the day before arrival. Twelve lead ECG and Right-sided ECG and Angiography shots of RCA are shown.

What is the most likely diagnosis?

85 y/o man came to emergency department complaining of episodes of palpitation. He had echocardiogram in his documents stating that he had a LV ejection fraction about 15%. ECG was shown:

what is your most likely diagnosis?

A 60 y/o lady came to ED with dizziness and pre-syncope. She had history of CABG+MVR+TV reapir. 

Two sets of ECG shown

What is the best treatment?

A young patient underwent EPS for paroxysmal SVT, Parahisian Pacing maneuver is shown:

According to the result of this maneuver, what is the most probable Arrhythmia?

Below you can find the 3D mapping ablation of case 564. 

What statement is False?

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

What is the most probable diagnosis?

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

Which statement is WRONG?

A 58-year-old male with a history of AVR, underwent implantation of a dual-chamber pacemaker from the right side of the chest. At the time of implantation, before leads screwing (Attachment of Leads to Device header) and placing the pacemaker in the pocket , the atrial lead impedance was 650 ohms. After placing the pacemaker in the pocket, suturing, and dressing the wound, reprogramming was performed. This time, the atrial lead impedance was 1750 ohms. Chest X-rays of the patient during implantation and after implantation are available.

What is the most likely diagnosis?

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

What is the most likely diagnosis?

A 30 y/o man underwent catheterization for evaluation of congenital heart disease.

One shot of catheterization is shown:

Can you guess the catheterization course?

An 80 year old asymptomatic lady came with below ECG:

What is your diagnosis?

A 27-year-old gentleman with a known case of Tetralogy of Fallot with a history of VSD repair, PVR, and dual chamber ICD implantation due to VT 3 years ago came to our clinic with the chief complaint of frequent episodes of shock during the last 2 months.

Below is the analysis of his ICD during one episode of his arrhythmia:

What is the most probable 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?

35 y/o woman with history of previous valvular surgery, underwent Echocardiography for routine checkup.

Which statement is TRUE about patient?

A 44-years-old man with no past medical history was referred to ED due to general weakness and abnormal ECG findings (Figure 1). He did not take any medication. On physical examination, deformity of the extremities was evident (Figure 2). A brain CT was done due to suspicion of intracranial hemorrhage showing severe basal ganglia calcification (Figure 3).

What causes ECG changes?

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 40-year-old woman has been complaining of refractory HTN for the last year. She goes to the heart clinic. After taking three classes of antihypertensive drugs, her blood pressure is still not controlled. Additional imaging is done for the patient, who is a candidate for renal artery angiography.

Based on the diagnosis which sentence is false?

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:

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

Which diagnosis is NOT probable?
