4Irregular Heartbeat
Increased pressure in your heart due to pulmonary hypertension would lead to a racing heartbeat. This indicates that your heart and surrounding muscles have to work harder to pump blood to other parts of the body. In normal people, the pulse range is often from 60 to 100 beats each minute. Thus, if your heart rate is more than 100, it might be a clear sign of pulmonary hypertension or similar conditions. This can be checked easily by taking the pulse with your ring finger and index. If left untreated over time, this symptom would make heart muscles weaker and cause heart palpitations, racing pulse, or erratic heartbeat. [4]
