The systole is when the left ventricle contracts and produces a stroke volume that is felt as a pulse. This is part of the measurement of a blood pressure reading. The reason you hear the 'lubb' sound is because the ventricle contractions are stronger than the atrial contractions. The 'dupp' sound is when the ventricles relax, so the sound is softer. Both sounds, or small upward blips on the sphygmomometer dial is due to the closing of, first, the atrioventricular valves for systole, and then the closing of the pulmonary semilunar valves for the diastole.
What else can I help you with?
What is the Apical Anteroseptal wall?
The Apical Anteroseptal wall is a thin wall and is a kinetic. This wall is thicken mildly during the process of systole.
What are the two qualities of the heart beat which must be observed?
diastole and systole diastole and systole
What is the pulse you hear on the chest?
Apical pulse
What is the contractual phase of the heart beat?
The contractive phase of the heart beat is systole.
What is the name of the muscles used in heart beat?
The muscles used to produce a heartbeat are called the "heart."
Will the apical beat be shifted in left ventricular hypertrophy?
Yes, in left ventricular hypertrophy, the apical beat may be shifted laterally and inferiorly due to the increase in left ventricular mass and displacement of the apex by the hypertrophied myocardium.
What is the normal rhythm of the apical beat?
pattern of stress oand unstress ...
Why can you only feel one pulse and the doctors can hear two?
When a doctor listens to your heart he hears the systole and diastole of the heart. The "lub-dub" that they hear is the closure of valves of the heart at rest (diastole) when the heart fills with blood and the heart squeezes blood (systole) out into the body. When you feel the pulse, you only feel when the heart pushes blood through the vascular system during systole.
What is apical thrust?
Apical thrust is a geological term that refers to the phenomenon where a fold or thrust fault in the Earth's crust moves in a direction towards the Earth's surface due to tectonic compression. It commonly occurs in mountain-building processes where rocks are pushed upwards and outwards.
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is the contractive phase of heartbeat?
systole
Apical beatcan best be heard?
The apical beat can best be heard at the apex of the heart, which is located in the fifth intercostal space at the midclavicular line. This is where the left ventricle is closest to the chest wall, making it easier to listen to the heart sounds.
