ECG Quiz: Questions: Salient findings and interpretation. If this patient had pulmonary stenosis, what would be estimated right ventricular systolic pressure?

Neonatal atrial flutter is a rare arrhythmia of the newborn. Often the fast heart rate in the fetus is considered a sign of fetal distress. In this ECG

In dextro transposition of great arteries (D-TGA), there is: Correct answer: 1. Atrioventricular concordance and ventriculoarterial discordance

ECG showing right bundle branch block. Right bundle branch block is characterised by an RSR’ pattern with the R’ being slurred, producing a QRS duration of 120 msec

PR segment depression and PR-ST dissociation PR segment depression can occur in pericarditis and atrial infarction. Dissociation between PR and ST segments (PR-ST dissociation) can occur in pericarditis.

Non invasive ablation of VT: In a potentially path breaking report published in the New England Journal of Medicine, non invasive cardiac radiation for ablation of ventricular tachycardia in 5 patients

Genetically engineered biological pacemakers could be a possible alternative to implantable electronic devices for the treatment of bradyarrhythmias.

Short run of ventricular tachycardia and atrial fibrillation: Underlying rhythm is atrial fibrillation as there are no P waves and it is an irregular rhythm.  Short run of wide

Since defibrillation involves the delivery of a high voltage shock, multiple high voltage shocks can cause some damage to the heart muscle.

The funny current or pacemaker current is predominantly a feature of the sinoatrial node.
