i want to know what is diastolic depolarisation in heart
210687
Cardiac Diastole is the period of time when the heart relaxes after contraction in preparation for refilling with circulating blood. Ventricular diastole is when the ventricles are relaxing, while atrial diastole is when the atria are relaxing. Together they are known as complete cardiac diastole.\n\nDuring ventricular diastole, the pressure in the (left and right) ventricles drops from the peak that it reaches in systole. When the pressure in the left ventricle drops to below the pressure in the left atrium, the mitral valve opens, and the left ventricle fills with blood that was accumulating in the left atrium. Likewise, when the pressure in the right ventricle drops below that in the right atrium, the tricuspid valve opens, and the right ventricle fills with blood that was accumulating in the right atrium.\n\nnever heard of the depolarisation but though, sorry!

Tachycardia (more than 100 beats per minute [bpm]) can be an indicator of heart disease.\n\nTemporary increases in heart rates in generally healthy people are not considered harmful to the human body.

it is an abnormal heart beat\n\nif it worries you go to your doctor who can check it out

Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats/minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats/minute. The action potential responsible for this rhythm arises from the sinus node and causes a P wave on the surface ECG that is normal in terms of both amplitude and vector. These P waves are typically followed by a normal QRS complex and T wave.

How old are you? Have you got any chest pain???\nVery similar to the signs just before a heart attack

"The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the myocardium (muscle of the heart). When the myocardium is stimulated, it contracts. It is the ordered stimulation of the myocardium that allows efficient contraction of the heart, thereby allowing blood to be pumped to the body.\n\nUnder normal conditions, electrical activity is spontaneously generated by the SA node. This electrical impulse is propagated throughout the right and left atria, stimulating the myocardium of the atria to contract. The conduction of the electrical impulse throughout the atria is seen on the ECG as the P wave."\n\n"An electrocardiogram (ECG or EKG, abbreviated from the German Elektrokardiogramm) is a graphic produced by an electrocardiograph, which records the electrical voltage in the heart in the form of a continuous strip graph."\n\n"An ECG measures the electrical potential between leads placed on various points of the body."\n\n"The leads measure the average electrical activity generated by the summation of the action potentials of the heart at a particular moment in time."

It is an electrocardiogram.  It  monitors the electrical activity of your heart, reveals your heart rhythm and your heart rate.  It is completely non invasive and not painful.  You will have to open your shirt so they can apply 12 leads (8 to your chest, 1 on each arm, and 1 on each leg) with sticky pads.  After the leads are applied they will ask you to lay still and it will record your hearts activity.  The whole process should take less than 5 minutes.

Sounds like WPW sydrome, or atrial fibrilation.  Go to a cardiologist and get an EKG.

This isn't really a question, but a test result. What is shows is a heart that has decresed blood supply that causes changes in the EKG, which is the electrical output of your heart with exertion. \n\nThe marks on an EKG are labelled P-QRS-T. The P is the contraction of the upper chambers of your heart, the QRS is the contraction of the larger lower chambers of the heart, and the T is the relaxation phase of those lower chambers, called the ventricles. The lead numbers and letters represent directions through the heart, and which ones have changes show the cardiologist what areas have decreased blood supply. "ST" changes are the place in the PQRST the hungry muscle shows up. "Ischemia" means dimininshed blood supply.\n\nThis usually means the coronary arteries which feed the heart blood have a blockage or other restriction of flow, from clots, build up of plaque or other damage. \n\nMore tests are needed to determine what kind of problem exists. A nuclear scan would show whether muscle has already been permanently damaged  or if it is possibly reversible. The "gold standard" would be a heart catherteriztion to map the exact problem, and even fix it with a balloon or by placing a stent.\n\nA test result like this one indicates a need for more follow up and whoever has this needs to promptly follow up with a cardiologist, preferably an interventional one. It's not a time to panic but to take necessary action.\n\nHope that answers some of your question, but this should be discussed with the doctor until you are satisfied with what it means.

heart rate is defined as the number of beats( systoles) the heart produces per unit of time( ussually per minute).\nBlood pressure is the pressure exert by the blood to the vessel´s walls( the arteries and the veins).

Better visit a cardiologyst..

Basically Blood Pressure measures your heart. The top number is the systolic number and measures the pressure exerted from the left ventricle of the heart. This is where the heart pumps the blood to the body. So when the heart contracts, this is the force. The bottom number is the diastolic number, this is when the heart, left ventricle is at rest. So you can see blood pressure measures the pressure. There could be numerous reasons for this reading. Personally I would see a doctor and see what the underlying cause is, maybe it is normal for you, but I would get it checked out.\nThis is on the lower end of the reading.  They say the systolic should be between 80 and 110, use to be 120 but they recently changed it.  My wife has the same thing, here pressure use to be around 110 and now it is in the lower 80's.  That's just the way her blood pressure.  Again see a doctor and maybe this is OK for her, but on the other hand it could indicate another problem going n with her body and should be checked out just to make sure.

chest and arm pain... when it comes together ,it' sa heart condition.EKG shows only what is happening when you do it.\ndon't delay it.run to to the service available in your country.\nno joking with it  .Sorry to frighten you,it has happened in my family.best wishes

The EKG estimates the net vector (in two dimensions) of the electrical activity of the heart; from the direction that the V1 lead looks (Above and to the right of the heart, as I recall laying out the electrodes years ago), the electrical activity is going away from the lead--towards the feet, or in the QRS part (the really big deflection), it's going from the AV node toward the tip of the ventricles.  That would be read as a negative direction.\n\nRemember, at every instant in time, the EKG is recording the equivalent of the dot product between the actual vector of the flow of current (so to speak) in the heart, and a vector that is created by connecting the leads in question.  For the V1 lead (a precordial lead), the leads connected to the limbs are used as a single lead, sort of grounding things out between all four of them (think of it being a lead somewhere behind the belly button, if you want), and then measuring the dot product of the electrical vector and a line connecting the V1 position with that.\n\nA little vector algebra makes this a LOT easier!

if i knew what EF meant it would help. if you're still worried about your heart, ask about a myoview or cardiolite test.

because these are the only two measurements done with a routine manual blood pressure reading.  now if on a blood pressure monitoring machine, there is a mean or average blood pressure.  however, the basics are the top number or systolic and bottom number or diastolic.  the systolic is the heart when working or contracting; the diastolic is the heart at rest.  a high diastolic is more significant due to the fact that a hi diastolic creates more pressure in the arteries to move the blood to vital organs.
