A 35 years old man, presented by recurrent palpitations. Below you can see two traces from 24 ECG Holter monitoring and also a trace during Electrophysiology study.

Regarding these traces, which diagnosis is less likely?

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?

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

A 68-year-old woman with history of diabetes mellitus, peripheral arterial disease, and breast cancer is referred to your outpatient clinic for decision regarding antithrombotic agents. In laboratory findings, creatinine and platelet count were 0.9 mg/dL and 88,000 × 10⁹/L, respectively.

She was receiving Aspirin 80 mg daily, Rivaroxaban 2.5 mg BD, Pantoprazole 40 mg daily, Atorvastatin 40 mg BD, and Empagliflozin/Linagliptin 10/5 mg daily. Her chemotherapy regimen was Docetaxel + Carboplatin + Trastuzumab.

Which is your preferred antithrombotic regimen?

A 55-year-old lady known case of hypothyroidism came to ER with a history of Transient loss of consciousness for about 30 seconds on the last day.
The episode was non-traumatic, abrupt in onset and she was in the sitting position.
She was complaining of dizziness that started 2 months ago.
Her initial Lab Data and Thyroid Function test was normal.
Her ECG is shown below.

What is the diagnosis and what is your next plan?

An 20-year-old woman experienced syncope at home and was transported to the hospital by EMS. Upon arrival in the ER, her GCS score was 10, and the emergency physician noted pupil dilation in both eyes. Her medical history revealed no cardiac problems, either personal or familial. The only significant finding in her history was the use of oral contraceptive pills (OCP). This is her ECG. 

What is the next step?

You are visiting a patient with a dual chamber ICD. Tracing of arrhythmia event is shown.

What is the rhythm and what is the result of therapy?

A 65 years old man came to ED with dizziness, his medication was as follow : Rivaroxaban 20 mg daily, Losartan 25 mg BD, Atorvastatin 40 mg daily, Amlodipin 5 mg daily. ECG is shown:

What is the Rhythm? what is your next plan?

The patient is a case of HOCM , you will see part of ECG Holter monitoring.

What is the rhythm and what is your decision for the patient?

A 24-year-old man arrived at the emergency department complaining of pleuritic chest pain that commenced shortly after the initiation of playing tennis.

The patient's vital signs were documented as:

Blood pressure: 100/50 mmHg
Heart rate: 105 beats per minute
Respiratory rate: 18 breaths per minute
Temperature: 36.5°C

Those are the initial ECG that was taken 10 minutes after arrival:

What is the best next management strategy?

 You were on an on-call duty. The emergency department nurse paged you because of cardiac arrest at ED. The ECG of patient at arrival is shown:

Which one of the following statement is the most suitable diagnosis for this ECG?

A young man experiencing palpitations underwent Electrophysiological Study (EPS), revealing the presence of two distinct arrhythmias, as illustrated below:

Which potential diagnosis is considered LESS likely?

A 45 y/o lady underwent RF ablation for a focal Ventricular Tachycardia. A tracing is shown.

What EP tracing show us?

65 years old lady with complains of dizziness and palpitations and syncope. Three ECG tracings are shown:

What is the most probable diagnosis?

A 58 y/o woman with history of seizures and pulmonary hypertension is admitted to the CCU with chief complaint of shortness of breath, palpitation, and worsening dyspnea on exertion. Also, she endorsed one episode of syncope. Right heart catheterization showed MPAP of 64 mmHg. In laboratory findings, NT-pro-BNP was 1,240 ng/mL. She was receiving carbamazepine 200 mg BID (for 15 years), amlodipine 10 mg daily, and macitentan 10 mg daily (for 6 months) at the time of admission.

What is your suggestion for the pharmacotherapy of PAH in this patient?

A 64-year-old male with a past medical history of CRT-P implantation 5 years ago,(with no medical record document) came to ER with chief complaint of syncope yesterday at 5 pm.

Here you can find the ECG and the arrhythmia episode concomitant with the syncope event.
What is the best choice?

A middle-aged man with frequent PVC, LVEF=35%,  and previous unsuccessful ablation in another center underwent RF ablation with the guide of Precision.

Where is the source of origin of PVC?

A 45 years old women came to office with mildly positive MPI scan. She was worried about the results. She was hypertensive with family history of premature coronary artery disease. Cardiologist decided to perform coronary angiogram. 
Angiogram is shown:

What is the diagnosis and the appropriate treatment strategy? 

Below you can find the EP tracing of a patient with narrow complex tachycardia.

Which one is not present in the tracing?

A middle-aged patient underwent EPS ablation for flutter. See the procedure summary below :
