Heart

Well the monitor piece worn around your chest has sensor pads that must be in direct contact with your skin for the unit to work. Data from the monitor piece is usually sent wirelessly to the data display / recording piece.also Forerunner 301 has a built-in receiver that works with the monitor strap provided with the unit. It must be within about 3 feet to receive signals from the monitor strap. 4rm:zero_689

How Heart Rate Monitors Work

The best heart rate monitors must make contact with your skin in order to work well and give highly accurate readings. These types of heart rate monitors are worn around the chest, secured with a strap. The monitor rests just below the breast, and contains a sensor that can read the electrical activity of your heart. The monitor also contains a transmitter. After the sensor reads the heart rate, the transmitter sends that information to a display, which can be worn around the wrist like a watch. The display shows your heart rate. Some heart rate monitors come with headphones, which are used instead of a wrist display. The monitor instead "tells" you your readouts. This way, you don't have to slow down or stop in order to read a digital display.

Heart Rate monitors: The most accurate heart rate monitors use a chest strap which fits snugly around your chest just below the breast. The transmitter detects the electrical activity of your heart just like an ECG. It relays this to a display, usually worn like a wristwatch, although some use earphones instead. It is important for the strap to maintain contact or you get wild readings.

Heart rate monitors work similarly to EKGs in that they measure the electrical activity produced by the heart. Find out how the leads on a heart rate monitor pick up electrical activity with information from a cardiologist in this free video on cardiology and the heart.

Congestive Heart Failure

These chords are called the Chordea Tendinae. Their function is to stop the valves from invertung back into the atria. If they weeken and stretch they start to allow the valves to be pushed back into the atria, this is called floppy valve syndrome.

Brain surgery is more riskier it is just my hunch my gut feelilngs surgeons can transplant a heart but to date cannot transplant a brain.

You mean a hatrick when a player scores 3 goals in one match.

Things like: Coffee and tea, drugs, being hot, dehydration can causes heart palpitations A hert palpitations is causes in the heart when the cells of the heart discharge electrical impulses too early before the next sinus beat and this can causes heart palpitations and extra heart beats.

Yes. he is in Lavasani 241 ( Farmanie ) next to te sportsclub. I visited him when I was seeing Dr Keyhani ,my dentist in the same building. They are both very busy Doctors.

The brain does not send the electricity to the heart. The heart is myogenic which means it can contract and relax without any stimulus from the brain.

it depends on the frog. i think that each frog has a different size

Extrasystole is due to the irregular contraction of the ventricle before the atria. When this happens, an action potential is elicited and the ventricle contracts. The action potential had a refractory period, during which the intrinsic heart rate attempts to fire but cannot elicit a contraction. This is why extrasystole is often referred to as skipping a beat. The compensatory pause is the time it takes for the beat to resume normal contraction.

The apex

Heart block is the term meaning interruption of electrical impulses in the heart's conduction system.

right ventricle

arteries

Noradrenaline is released when the medulla oblongata sends impulses along the nervous system and when the chemical reaches the S.A node (pacemaker), the noradrenaline makes the node fire more rapidly. Acetylcholine reaches the S.A node, and slows down the firing of the S.A node.

I would like to know what the apical segments of the anterior wall and apical septum are?

The left side of the heart has a thicker ventricular wall.

The left ventricle is responsible for pumping oxygenated blood into the aorta, thereby providing oxygen to all parts of the body. The right ventricle, in contrast, only has the responsibility of pumping de-oxygenated blood into the lungs for the exchange of gases, which requires less pressure than pushing blood through the entire body.

Cardiac Arrest.

its part of the circulatory system that the heart pumps blood to all parts of the body

The right side of the heart receives blood from the body. The left side receives blood from the lungs.

The heart has three surfaces: anterior, inferior and posterior. The anterior, sternocostal surface, the inferior or diaphragmatic surface and the base of the heart, the posterior surface.

The opening and closing of the heart valves.

I can't answer this, that's why I asked this site, but obviously this site is stupid,so shove that in your pipe!
