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

What is the most probable diagnosis?

A 59-year-old male was admitted to our emergency department with general weakness. He had been a heavy smoker (45 packs per year); however, he denied any past medical conditions and taking medication. On examination at first hospitalization, he was afebrile with respiratory rate, and blood pressure of 16 breaths/Min and 125/74 mmHg, respectively. He has a widespread wheeze of auscultation of the chest. 

What is the best next plan?

A 39 y/o female patient admitted to ED complaining of sudden onset episode of chest pain, bed side echocardiography showed LVEF about 35 %.

Two ECG tracings & Coronary angiography were shown:

At the time of your visit the patient was asymptomatic, which one of the following options is NOT an appropriate management plan for this patient?

A 31 y/o lady underwent Echocardiography for evaluation of systolic murmur with fixed S2 splitting. Echocardiography is shown:

What is your most likely diagnosis?

A 37 y/o male patient presented to the ER with prolonged weakness, episodes of chills, fever and dyspnea from 1 month ago and headache during the last weak.
his PMH was unremarkable but in physical examination signs of multiple intra venous injections were obvious. 

below you can find his chest and brain CT scan and echocardiogram 

Besides initiation of antibiotics, what is the best choice? 

A 79-year-old man with a history of complete heart block and pacemaker implantation in 2020 without coronary artery evaluation. He is currently hospitalized with NSTEMI and is a candidate for coronary angiography.

According to the following ECG strip (Figure 1), what is the most probable diagnosis?

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 60 years old man with sustained arrhythmia and low LVEF (ECG below) underwent EPS and RF ablation, propagation mapping of right atrium and ECG is shown: 

In regard to ECG and propagation mapping of RA, what is the possible arrhythmia?

A middle-aged lady with frequent paroxysmal palpitations, EP tracing is shown. (proximal CS is paced)

Which statement is FALSE? 

A middle-aged lady had EPS for several episodes of palpitations, An EP trace during RF ablation is shown:

What is inferred from this tracing?

A 40-year-old woman complained of heart palpitations;

Based on echocardiography, which option is wrong?

60 y/o woman with history of valve surgery and pacemaker implantation came to ED complaining of new onset dyspnea.

which statement is true about patient diagnosis?

A young lady with preexcitation underwent EP ablation. Post-ablation, Adenosine was administered to block the AV node and confirm successful accessory pathway ablation. Below is the tracing following the procedure: 

Which statement is wrong?

A 19-year-old patient was referred for an arrhythmia accompanied by traumatic syncope. The rest and arrhythmia ECG are shown:

What are the diagnosis and best choice of treatment?

A 54 years old man with a history of STEMI and primary PCI months ago presented with palpitations, Rest ECG and the arrhythmia ECG are shown : 

What is the most possible diagnosis?

Below is the printed report of a device implanted in a young patient with Brugada syndrome.

Which statement is wrong about this case?

A 68 years old lady underwent CRT-D implantation. Biventricular pacing is could not be achieved after implantation Fluoroscopy and chest X-Ray of the patient are given. ECG after implant also given:

What is wrong with the device?

A 57-year-old man is transferred by EMS during the night with persistent chest pain since the afternoon to the emergency department of a non–PCI-capable hospital, located 3 hours away from the nearest PCI center.

Past Medical History:

• Diabetes mellitus (DM)

• Hypertension (HTN)

• Hyperlipidemia (HLP)

• Cigarette smoker (CS)

• Opium addict (OA)

• Previous intracranial hemorrhage (ICH)

Assessment on Arrival:

• Vital signs: HR 90 bpm, BP 85/55 mmHg

Based on the patient’s condition, what is the most appropriate next step in management?

A 55-year-old man with palpitations and WCT on surface ECG and history of successful previous VT ablation, referred for ablation. Surface ECG is shown:

Where is VT origin?

Below you can find the ECG of arrhythmia and CS venogram during RF ablation.

Where is the ablation catheter and what was the target of ablation?
