2. Tachycardia - Wikipedia

   en.wikipedia.org/wiki/Tachycardia

   Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).

3. Cardiac arrest - Wikipedia

   However, structural changes in the diseased heart as a result of inherited factors (mutations in ion-channel coding genes, for example) cannot explain the sudden onset of cardiac arrest. [60] In ventricular tachycardia, the heart also beats faster than normal, which may prevent the heart chambers from properly filling with blood. [61]

4. Palpitations - Wikipedia

   The onset of palpitations is sudden, with the acceleration of the heart rate occurring within a single beat, and may be preceded by a feeling of the heart skipping a beat. The heart may continue to race for minutes or hours, but the eventual termination of the arrhythmia is as rapid as its onset. [1]

9. Arrhythmia - Wikipedia

   en.wikipedia.org/wiki/Arrhythmia

   Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia.
