Symptomatic Bradycardia

The determination on whether or not treatment is necessary for bradycardic events is generally based on the presence of symptoms. The clinical manifestations of bradycardia can vary widely from insidious symptoms to episodes of frank syncope.

Atrial Fibrillation

Atrial fibrillation (AF) is an abnormal rhythm caused by the rapid firing of multiple cells in the atria, the upper chambers of the heart, which cause the atria to quiver ineffectively. Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice and is associated with increased risk of stroke, dementia, falls, and death, among other outcomes.

Ventricular Fibrillation

Ventricular fibrillation (VF) is the most common initial heart rhythm in patients with out-of-hospital cardiac arrest (OHCA), and the most salvageable one. Although VF appears as a chaotic and disorganized rhythm, characteristics of the ventricular fibrillation waveform such as amplitude, frequency, and organization can be systematically quantified in real-time.

Pulseless Electrical Activity (PEA)

All pulseless rhythms that fall outside the category of pulseless ventricular tachycardia, ventricular fibrillation, or asystole are considered PEA. Learn more!

Atrioventricular Blocks

AV blocks are conduction delays or a complete block of impulses from the atria into the ventricles. Learn more about their diagnosis, and the different types of AV blocks.

Vagal Maneuvers with Supraventricular Tachycardia

Vagal maneuvers are used as a first-line management tool with supraventricular tachycardia. Learn how this tool can and should be used.

Shockable Rhythms

According to television, if there’s a heart problem, you shock it. WRONG! Learn about shockable rhythms.

Becoming Familiar with Synchronized Cardioversion

For certain types of cardiac arrhythmias, synchronized cardioversion can be an effective treatment. Learn about synchronized cardioversion and the differences between it and defibrillation.
