Understanding Cardiac Arrhythmias and ECG Interpretation Quiz

Normal rhythm characterized by atrial depolarization preceding ventricular depolarization.

Elevated heart rate originating from the sinus node, often due to physiological stress or excitement.

Provides a view of the right ventricle, crucial for detecting infarctions.

Provides a view of the left ventricle and is commonly used to assess for ischemic changes.

Provides a view of the right ventricular wall, useful for detecting posterior wall infarctions.

Impaired transmission of electrical signals from atria to ventricles.

Irregular heart rhythm with chaotic atrial activity and no discernible P waves.

Provides a view of the septum and right ventricle, useful for detecting infarctions.

Heart rate below normal, often below 60 beats per minute.

Duration from onset of atrial depolarization to onset of ventricular depolarization.

Chaotic, irregular ventricular rhythm leading to rapid cardiac collapse if not treated immediately.

Low potassium levels leading to delayed repolarization and QT interval prolongation.

Rapid, regular heart rhythm originating in the ventricles with widened QRS complexes.

Pre-excitation syndrome characterized by a slurred upstroke of the QRS complex.

Regular atrial rhythm with a characteristic 'sawtooth' appearance.

High potassium levels leading to rapid repolarization and peaked T waves.

Atrioventricular dissociation with prolonged PR interval and dropped beats.
