A pulse rate of 95 to 100 beats per minute is considered normal and when it exceeds 100 beats per minute, it is considered tachycardia. Pulse is a palpable arterial beat in the human body. A normal person’s pulse is the same as the heart rate, with a normal range of 60 to 100 beats per minute. The pulse rate is related to age and gender, and is slower in older people. When an adult’s pulse rate exceeds 100 beats per minute, it is called tachycardia. Common types of tachycardia include sinus tachycardia, supraventricular tachycardia, ventricular tachycardia, etc. Typical symptoms of tachycardia include palpitations, tightness in the chest, shortness of breath, and discomfort, and in severe cases, it can lead to low blood pressure presenting as a headache and dizziness, blackouts, and fainting. When patients experience symptoms such as palpitations and dizziness, they should go to the hospital immediately.
