The 33-year-old man, with a previous medical history of thymic lymphoma and having undergone chemotherapy two years ago, showed no detectable malignancy in a PET scan one year ago. His recent presentation to the emergency room complaining of dyspnea prompted further investigation. Notably, physical examination revealed a muffled heart sound and prominence of the jugular venous pressure (JVP). Subsequent echocardiography indicated the presence of massive pericardial effusion accompanied by a swinging heart.

In the management of this condition, pericardial fluid was drained from the patient. Regarding the analysis performed on the drained fluid, which of the following options is incorrect?

Pericardial Fluid:

- Cholesterol: 107 mg/dL

- Triglycerides (TG): 1027 mg/dL

- Lactate Dehydrogenase (LDH): 140 U/L

Serum:

- LDH: 154 U/L

- Cholesterol: 120 mg/dL

A 35 years old man with palpitations and low LVEF=40%, ECG and Holter tracings are shown:

What is your diagnosis and treatment plan?

A 60 years old man, Hx of Hypertrophic Cardiomyopathy, Mild CAD presented by recurrent palpitations converted to sinus rhythm with adenosine but reinitiate again. ECG is shown.

Which diagnosis would be most probable?

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 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?

An 18-year-old girl presented to the emergency room with a syncope episode while seated, lasting 20 seconds.

 Considering the echocardiography and electrocardiogram (ECG) findings, which diagnosis is unlikely?

A middle-aged patient with history of AVR, symptomatic PVC (30%) unresponsive to beta-blockers and Sotalol. ECG is shown: 

What is your plan? 

A 25-year-old patient came to our clinic with the chief complaint of palpitation, based on his surface ECG, we scheduled him for EPS.

According to his surface ECG and EP tracing, which statement is not true?

Below you can find EP tracing of a patient with paroxysmal AF who underwent cryoballoon AF ablation.

what happened?

A 30 y/o woman underwent echocardiography for evaluation of dyspnea. She claimed that her dyspnea worsens while lying on the left side.

What is the most likely diagnosis?

27 years old girl underwent EPS for palpitation. An EP tracing during EPS is shown.

Which statement is TRUE about this tracing?

A 72-year-old male with a history of CABG 10 years ago and PPM-DR implantation last year due to CHB presented to the ER with a chief complaint of fatigue and dizziness persisting for the past month. Bedside echocardiography revealed an ejection fraction (EF) of 30-35%, moderate mitral regurgitation (MR), and no pericardial effusion.

Based on the ECG findings, what underlying condition or situation could be LESS responsible for these symptoms?

Below are the electrophysiological (EP) tracings of a 42-year-old patient presenting with the primary complaint of palpitations:

Which statement is FALSE?

A young man experiencing palpitations and presyncope in the ER was treated with Procainamide. See his ECGs below:

Which statement about his EP procedure is TRUE?

A 50 y/o female patient admitted with atypical chest pain.

ECG is shown:

The ECG findings are most consistent with which ONE of the following diagnoses?

A middle-aged man underwent a coronary angiogram, below you can find angiography and concomitant 12 lead ECG:

What is your diagnosis?

A young lady with minimal preexcitation underwent EPS, EP tracings are shown below

What is the possible diagnosis?

A 16 years old girl with palpitations underwent EPS and ablation. Below you can find tracings of normal sinus rhythm and tachycardia and also EP tracing of the patient.

What is FALSE about this case?

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

Which statement is NOT correct?

A 70 y/o man with left upper quadrant and hemothorax pain from last night 

He had performed EVAR last year due to Abdominal Aorta Aneurysm

Bp:100/70 PR:100/min  RR:18  Room air O2 sat:94%

WBC:12700 PMN 78% Hb:6.7 PLT:177000

Cr:1.7, Negative Tn

Abdominopelvic CT with IV contrast was done

What is your diagnosis and treatment?
