What statement is wrong?

A 35 y/o man is candidated for ETT for evaluation of his chest pain. His baseline ECG  before ETT was shown:

What is the Rhythm?

A young man with palpitation underwent EPS. An EP trace is given:

Three beats are marked, explain each of them separately :

Below you can find the sparkle mapping of a case of unsuccessful CCW flutter ablation.

what is the wrong statement? 

A 50 y/o male patient was admitted in the ICU, due to severe head trauma. He was unconscious (GCS:6) and his past medical history was not clear.
His SBP was 145 mmHg at the time of admission.Emergent craniotomy and hematoma drainage was performed and he was stable in the first day.

Cardiology consult was requested due to rise in Troponin level and ECG changes. 
In day 2, he became hypotensive, that was refractory despite initiating vasopressor agent.
You can find brain CT scan and ECG below.

What’s the best choice ?

A young lady with palpitations, surface ECG showed preexcitation. 

Where is the location of the accessory pathway?

A 62 years old lady with history of previous flutter ablation, she was candidate for Precision 3D mapping RF ablation, EPS and ablation is shown below:

Which statement is False about the procedure?

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

Which statement is NOT 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?

An angiogram of the right coronary artery is shown with concomitant 12 lead ECG.

What happened and why? 

35 years old man with recurrent palpitations, underwent EPS. Two tracings are shown below.

What is the most likely diagnosis?

Which statement is NOT correct?

Below you can find a "plot diagram" of a patient with an ICD. 

Which statement is WRONG?

A 60 years old male with pmh of CRT-D implantation last year,presented with this ECG. he had episodes of dizziness.
the ECG and CXR are shown below.

Which statement is correct?

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 78 y/o woman came to ED complaining of acute onset of retrosternal chest pain, she was anxious and suffer from severe chest pain. In her past medical history she only had a history of hypertension.at admission to hospital her vital signs were as follow:

BP=160/60  HR=110 RR=22 O2sat in room air=96%

an ECG &bed side echocardiography was done immediately

According to ECG &echocardiography what is your next appropriate step?

A middle-aged lady came with palpitations, three ECGs are shown below:

What is your diagnosis?

A 17-year-old male with no significant past medical history presented with the chief complaint of palpitations. His surface electrocardiogram (ECG) and electrophysiological study (EPS) are illustrated below:
