A rapid or fast heartbeat, medically known as tachycardia, occurs when your heart is beating faster than the normal resting rate. For adults, a normal heart rate is typically between 60 to 100 beats per minute (bpm). When the heart rate exceeds 100 bpm, especially if it's sustained, it's considered tachycardia. This elevated heart rate can be triggered by various factors, including stress, anxiety, medications, excessive caffeine intake, or physical exertion. However, it's important to note that a fast heartbeat can also be a sign of an underlying heart condition, such as arrhythmias, heart disease, or even a reaction to an illness or injury. It's crucial to consult with a healthcare professional if you experience a persistent rapid heartbeat, especially if it's accompanied by other symptoms like dizziness, shortness of breath, or chest pain. read more >>
