An abnormally fast heart rate that begins in the upper chambers of the heart is called atrial or supraventricular tachycardia (SVT). Instead of this rhythm occurring in the heart’s natural pacemaker, the sinoatrial node, it travels through a different pathway present since birth.1,2 Ventricular ...
While bradycardia describes when the heart rate is too low, tachycardia describes when one's heart rate is too high, which generally means the resting heart rate exceeds 100 bpm, according to theNational Institutes of Health. This generally occurs when electrical signals in the heart's upper cha...
Learn about sudden cardiac arrest, an electrical problem with the heart that triggers a dangerously fast heart rate.
Christina Applegate's daughter Sadie recently revealed she was diagnosed with Postural Orthostatic Tachycardia Syndrome, or POTS, prompting questions about the condition. POTS causes your heart to beat faster than normal when you go from sitting or lying down to standing up, according to the ...

Rate control: Rate control focuses on slowing down the elevated heart rate. Rhythm control: If patients still experience symptoms when their heart rate is under control, doctors will try to normalize the heart rhythm. Stroke prevention: Preventing the formation of blood clots in the heart. Treatin...
