Yes, a person can have a cardiac arrhythmia, which is a problem with the heart's electrical system, and pulmonary hypertension, which is abnormally high blood pressure in the arteries of the lungs.
An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
When the small arteries of the lung become narrowed, they cannot carry as much blood. When this happens, pressure builds up. This is called pulmonary hypertension.
I hope this answers your question,
