A 23-year-old man with palpitations and frequent PVCs on surface ECG and Holter monitoring (PVC burden: 41%), referred for ablation. Below you can find ECG and EP tracing (Figs. A and B). 

What is the most likely site of origin of the premature ventricular contractions (PVCs)?

A 43 years old gentleman with no remarkable past medical history, presented to the Emergency department with progressive weakness from 7 days ago.
He didn’t recall any pain or any other symptoms.

During first evaluations , his SBP was 250mmHg and his serum creatinine was 7 mg/dl. Based on his Chest X-ray, we performed echocardiography and CT angiography.

Below you can find CXR , CTA and echocardiogram.

What is your plan?

As a consultant physician, what is your opinion regarding the patient?

A middle-aged lady underwent EPS with 3D mapping, below you can see the 3D mapping of her arrhythmia :

Based on the 3D mapping, what is the possible arrhythmia?

A 68-year-old woman with the past medical history of aortic valve replacement (AVR), mitral valve replacement (MVR), and septal myectomy (2013), presents to the emergency department. She reports a two-day history of substernal heaviness. The onset of her symptoms coincided with a interpersonal conflict involving her daughter and son-in-law.

Her prior coronary angiography, performed at the time of her valve surgery, was reported as normal.

Based on the most probable diagnosis suggested by the ECG and echocardiography findings, which of the following choices is correct?

A 64-year-old woman, known to be hypertensive and on amlodipine, was diagnosed with breast cancer 6 months ago. She completed 6 cycles of chemotherapy, with the last one administered 4 weeks ago, in preparation for radical mastectomy and axillary clearance.

She presents to the cardiology clinic complaining of shortness of breath. On examination, her blood pressure is 105/80 mmHg, pulse is 90 bpm, and regular. Bibasilar crackles were noted on auscultation of her chest.

Her ECG showed non-specific ST changes in the anterior leads.

Based on this clinical presentation and the chest X-ray (CXR) shown below, what is your diagnosis?
