What's Causing Your Heart to Skip a Beat?
Published: Nov 08, 2023
Arrhythmias can make your heart feel like it's doing a backflip. Understanding what causes these rhythm disturbances is key to managing them.
Understanding Arrhythmias
An arrhythmia is any irregular heart rhythm that differs from the normal sinus rhythm. The heart usually beats steadily between 60 and 100 times per minute, controlled by signals from the sinus node. Arrhythmias occur when these signals get disrupted, leading to abnormal heartbeats that can be too slow, too fast, or irregular.
Common Types of Arrhythmias
In a typical office setting, you might encounter arrhythmias like premature atrial complexes, ventricular premature beats, or atrial fibrillation. While some arrhythmias require urgent attention, others might not need immediate management but could indicate underlying heart conditions. It’s important to differentiate which types pose a risk and need further evaluation.
Symptoms to Watch Out For
Symptoms of arrhythmias can include palpitations, dizziness, or even fainting. These symptoms might mimic other medical issues and can range from mild to severe. The severity often depends on how fast or slow the heart is beating and if there are any underlying heart conditions.
