Increased physical activity, anxiety, caffeine consumption and stimulant medications can cause a fast pulse, explains Healthline. Hyperthyroidism or heart arrhythmias can also trigger the condition, so it is important for individuals with unexplained symptoms to consult with a physician to ensure an accurate diagnosis.
Additional medical conditions that can trigger a rapid pulse rate include anemia, heart valve problems, kidney disease and heart failure, explains MedlinePlus. Pregnant women may also experience fast pulse rates due to excess fluid retention.
Individuals who are overweight and out of shape may experience faster pulse rates when engaging in strenuous physical activity, explains AARP. Making lifestyle changes, such as increased exercise and implementing a healthy diet, can often prevent symptoms. In certain cases, a rapid pulse can signify a heart attack, so it is imperative for individuals to seek immediate medical attention if symptoms are accompanied by heavy sweating, chest tightness, vertigo and confusion.
When a pulse rate is higher than 100 beats per minute, it is referred to as tachycardia, according to ATI Nursing Education. Tachycardia can signify several medical conditions that include congestive heart failure, shock and blood hemorrhages. Depending on the underlying cause of the condition, individuals with tachycardia may also exhibit symptoms such as fatigue and fluid retention.
