A 66 years old man with came to clinic for ICD analysis, Tracing is shown (1,2,3)
What is the tracing interpretation?
35 years old man came to the clinic with atypical chest pain. Echocardiography was performed.
Which statement is TRUE about this patient?
A 35 y/o woman came to your clinic complaining of occasional episode of palpitation, At the time of your visit she was asymptomatic but she had a ECG of the time of her palpitation with her.
According to ECG what is your most likely diagnosis?
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 30 y/o man underwent catheterization for evaluation of congenital heart disease.
One shot of catheterization is shown:
Can you guess the catheterization course?
44-year-old man, with no symptoms, but two siblings experienced sudden cardiac death. ECG is shown below. He had normal electrolyte levels and no apparent heart disease.
What option is NOT present in his ECG?
A young lady with palpitations. ECG of the arrhythmia is presented below.
Which diagnosis is NOT probable?
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?
This EKG was observed in a patient with myocardial infarction,
Which of the following statements about the arrhythmia shown in this EKG, observed in the setting of an acute myocardial infarction, is NOT correct?
A middle-aged man with MVR, EPS performed, Below are the findings: ECG during arrhythmia, EP tracings, fluoroscopic imaging, and sinus rhythm ECG.
What is the best explanation?
An 18 years old girl underwent EPS ablation regarding history of palpitations and presence of minimal preexcitation in ECG. Below you can find ECG and an EP tracing.
What is your idea about the location of accessory pathway?
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 50 years old lady with history of unsuccessful RF ablation underwent EP, Arrhythmia was easily inducible with programmed stimulation, below you can see surface ECG, Entrainment maneuver and also 3D mapping with precision:
What is the mechanism of arrhythmia?
A 34-year-old man came to our ED with the chief complaint of palpitation, here are two shots from the intracardiac EGM of his EP study :
What is the most probable diagnosis and the mechanism behind turning 2:1 arrhythmia to 1:1?
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?
A 80 years old woman came to ED with Dizziness and Nausea.
Past Medical Hx : DM,HTN,CKD,CVA
ECG is shown:
What is your best diagnosis and treatment for this case ?
A dual chamber pacemaker implanted for a patient. One hour after implantation, you called by a nurse for "strange rhythm". Two shots of Pacemaker analysis are given.
What is the problem?
A 71 years old man underwent Ablation for ischemic VT. An EP trace shown below.
Regarding EP tracing which statement is TRUE?
A 70-year-old woman experiencing dizziness; below are the ECGs captured over the course of one day.
Which option is NOT as accurate in this scenario?
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?
