Which statement is TRUE?

A 67-year-old male patient with a history of diabetes and hypertension came to our clinic with the chief complaint of DOE FCII from 3 months ago

His ECG is shown below

Echo: EF: 50 %, SPAP: 55,  Severe LVH, Diastolic Dysfunction Grade III, biatrial enlargement

CMR: RCM, Cardiac amyloidosis should be considered

We ordered Protein Electrophoresis with immunofixation which result is shown below :

M peak : 3.1 g/dl ( normal range < 3 g/dl )

What is the best next step?

A middle-aged patient underwent EPS and Ablation for incessant arrhythmia, below you can find 12 lead ECG and EP tracings of the patient.

What is the most probable arrhythmia? 

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?

A 39-year-old woman is experiencing paroxysmal palpitations. Below are the electrophysiological (EP) tracings.

What is the most probable diagnosis?

50 Y/O female presented to hospital complaining about recent exertional chest pain and episodes of syncope which mostly happened at the time of doing home laundry.

According to this aortography, Which one is the most probable cause of syncope in this patient?

A 72‑year‑old woman with a history of type 2 diabetes mellitus, ischemic heart disease, and end-stage renal disease on routine hemodialysis presents to the emergency department with malaise, generalized weakness, and nausea since last night.

On arrival:

• Blood pressure: 100/60 mmHg

• Pulse: 26 bpm, regular

• She appears fatigued but arousable.

Her ECG is provided.

What is the most appropriate immediate next step in management?

An ECG of an elderly man with fever is provided below.

Seeking the optimal explanation for this ECG. What's your take?

what are the diagnosis and treatment?

A 62 year-old-man was referred with a history of palpitations, LVEF=40%, and mild coronary artery disease. Two sets of ECG are shown.

Which of the option is NOT evident in these ECGs?

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 middle-aged man with frequent PVC and Low LVEF, below you can find EP tracing during PVCs and also ablation.

What statement is wrong?

A 52-year-old man with a past medical history of hypertension presents with dyspnea. Myocardial perfusion imaging demonstrates reversible ischemia in the anterior wall territory. Elective coronary angiography sequence is displayed below.

Based on the most likely diagnosis, which of the following options is incorrect?

This ECG is taken during the ablation of case no.459, divided by a blue bar into two segments.

There are subtle changes in ECG, what is your diagnosis?
