@medexplained3: ❤️ Sudden Racing Heart? It Could Be SVT. Have you ever been sitting normally when your heart suddenly starts racing? In this video, we explain Supraventricular Tachycardia (SVT) and the common factors that may trigger an episode. Stress, excessive caffeine, alcohol, lack of sleep, exercise, nicotine, certain medications and other factors can play a role in susceptible people. But remember: not every fast heartbeat is SVT. An ECG is needed to identify the actual heart rhythm. ⚠️ If a rapid heartbeat occurs with chest pain, severe shortness of breath, fainting, or severe dizziness, seek urgent medical care.
