In medical language, pulsus bisferiens is also known as bisferious pulse or biphasic pulse. Because Bisferious means striking twice, traditionally pulsus bisferiens is discovered when aortic insufficiency exists in association with aortic stenosis, but may also be found in isolated but severe aortic insufficiency, and hypertrophic obstructive cardiomyopathy.

Normally in central arteries, arterial pulses are best felt like brachial and carotid, but pulsus bisferiens is an exception to that and can be better felt in peripheral arteries like the radial artery. This type of pulse can also be felt better in peripheral arteries is pulsus alterans. The first lift is happened due to “percussion wave”(P) and the second lift is happened due to tidal wave (T). In different parts of heart bisferiens pulse can be seen in aortic stenosis which is accompanied by moderately severe aortic insufficiency. The pulse rises very slowly in aortic stenosis and the second wave of the double beat is the more forceful one

There are many causes which are associated with pulsus bisferiens. Defect in the rhythm of heart is the most common organic cause of bisferiens pulse. Many patients suffering with chronic aortic insufficiency are asymptomatic until ages 40 to 50. However, as a result of this defect exertional dyspnea, worsening fatigue, orthopnea and, eventually, paroxysmal nocturnal dyspnea may develop. In some cases, it commonly occurs with high output states, such as anemia, thyrotoxicosis, fever, and exercise. Some findings which are associated with pulsus bisferiens underlying many causes and may include moderate tachycardia, a cervical venous hum, and widened pulse pressure. Pressure gradient is the basic cause of pulsus bisferiens in 40% patients in the left ventricular outflow tract. Sometimes it is palpated and the pulse rises rapidly, and the first wave is the more forceful one.

It is basically dependant on the heart and if your heart is working properly then you won’t be in troubled by this disease and to keep the heart healthy you have to take good care of it. The diet should be appropriate and it should include all the ingredients which make your heart healthy and working properly. So if you don’t want to suffer from this fatal disease you should be keen toward your diet and heart anything unusual change or pain can lead you to pulsus bisfereiens.
