Study of the heart shows that human body is a complicated machine. This machine is far more advanced than can today’s artificial equipment. Medical practitioners are able to learn faster about the internal mechanism of the heart due to the availability of online learning resources. It is easy for the practitioner to provide consultation to heart patients via real time communication online. For details, one can refer to global health media videos.

Advanced scientific innovations draw inspiration f the complicated mechanism of the heart. Blood flows to and out of the heart. Valves in the heart controw blood flow. The process is analogous to the inside of a 4 stroke engine, where fuel enters through the inlet valve of the cylinder during intake stroke and effluent gases leave out in the exhaust stroke through exit port.

There can be a mechanical defect causing an error in functioning of the valves. If not diagnosed properly, the consequences can be severe.

Heart is a vital organ. Heart is responsible for delivering blood to all the organs of the body. This blood is oxygen and nutrient rich. The heart consists of two pumps working side by side with each other.

The structure of heart

Cardiology is the specialised study of heart. Cardiology is important for every person, not just the professionals.

Heart is situated in the centre of the body. Its position is slightly more towards the left since left part is larger than the right.

The right and left sides of heart are separated by a partition called septum. The upper section of each chamber is known as atrium, while the lower chamber is known as ventricle. The right side has right atrium and right ventricle. Similarly left side is divided into left atrium and left ventricle.
The right atrium is connected to 2 large veins i.e. superior vena cava.

The left ventricle is connected to the largest artery i.e aorta.
The aorta pumps oxygenated blood throughout the whole body.

There are four valves in the heart- tricuspid valve, aortic valve, pulmonic valve and mitral valve.

The atrioventricular valve is the connecting link between left atrium and left ventricle. It has 2 cusps and is hence known as bicuspid valve. A tricuspid valve connects right atrium to right ventricle. Medical experts call it as valve.

For more details and animated videos about the functioning of the heart, one can refer to global health media videos.

Knowledge about heart helps a person to prevent any diseases. A heart check up is a helpful activity and regular heart check-up will ensure the process efficiency of the heart’s biomechanics.

Heart impairments may be congenital or existing since birth. Else, heart impairment may result if there is a blockage in the flow.

Heart beat

Beat is caused because of the cycle of blood inflow and outflow. The heart beat rate is 60 to 100 per second. Fast heart beats indicate feeling nervous or a health impairment. Stethoscope is the handheld instrument

Stethoscope is the clinical instrument to verify if heart beat is proper.

A healthy human has a lub-dub heart sound. If the muscles in the heart are not strong enough, the sound will be different.
Nowadays, people have access to advanced biomedical equipment which provide in-depth analysis of blood flow rates and heart beat. Viewers have access to information resources and presentations by healthcare experts.

Medical and healthcare professionals need to understand the concept of heart beat. Heart is a subject for active research not oy for cardiologists but also biomedical engineers, pathologists, radiologists, medical team and other healthcare professionals.

The function of the heart

Heart requires its own supply of blood. Heart is similar to a large pump powered by its own electrical system.

Deoxygenated blood enters through the arteries into the heart via valves. The blood gets enriched with Oxygen and nutrient. This oxygenated nutrition rich blood flows out of the heart using valves and flows to all the parts of the body through veins.
The heart valves open only in 1 direction. Blood flow has to be unidirectional. Any leakage will cause backflow of blood, which is a metabolic disorder. Any fault will cause mixing of oxygenated with deoxygenated blood.

Heart lies at the prime centre of the circulatory system. Deoxygenated blood flows into heart through pulmonary arteries while Oxygenated from heart flows into lungs via pulmonary veins.

Heart impairments

Heart is highly delicate organ. So, a defect in heart may have dangerous consequences.

Improper flow of blood may lead to accumulation of fluids inside the lungs. Therapy of such a complicated needs intensive in-depth research. Even the patient must know the inside of his heart to be able to recover effectively. A heart patient must not panic at the mention of the exact heart defect. Identifying exact impairment is aimed at finding a therapeutic solution to the medical disorder rather than creating a trauma for the patient or his family.

Diagnostic techniques

Before therapy, the defect must be identified. Anybody facing irregular symptoms must report to the cardiologist who then recommends him for ECG screening. Electrical impulses are used to understand the heart’s mechanism. It is a non-invasive technique.

An electrocardiogramn(ECG) tests whether the heart beat is normal or not. Graphical information gets displayed on a computer screen. This graphical information is used by cardiologists to detect the exact disorder. Nowadays, cardiologists provide patients with one-on-one consultation using online discussion platforms where they share the ECG results and provide a detailed description.

Open heart surgery

It is an incisive technique where the team of therapists cuts through the chest and removes the obstacle causing a blockage eg. a bullet. One needs to be very meticulous and there must be least tissue damage during the incision. Surgical scissors must not be germ free. The therapists must use gloves during open heart surgery.

Cardiac rehabilitation

Even in the post treatment phase, patients should pay attention to the heart’s functioning. Cardiac rehabilitation includes many steps including performing gym workouts. The purpose of cardiac rehabilitation is to help the patient come out of the trauma of surgery and start leading a normal life. Patients should stay in touch with their therapists and share the graphical reports of their personal progress.


If the heart cannot function at all, the patient can opt for a pacemaker. The pacemaker is a biomechanical device. It can replicate the function of the heart. Thus it can oxygenate the incoming blood and enrich it with nutrients, just like a heart does.

A pacemaker is quite expensive. But still it is highly valuable. Patients must realise the value of their heart. Live streaming global health media videos helps medical team to consult with the patients remotely and explain them the significance of pacemaker in case of urgency.

Safeguarding patients from illicit medical practices

Informative videos help the patient get in touch with the right therapist. Anti-human activities like organ trafficking are a shame on mankind. The organs inside the body are highly valuable and trading them for money is an offence. There must be more transparency in the way therapists are conducting the treatment. Openness of communication is a must have for effective therapy and recovery from impairment.


Heart is a delicate and vital organ. It is the prime centre of the circulatory system. Defects in heart can be since birth or emerge later. Information about the cyclical function inside the heart is an eye opener for people even if they are not professionals. Global health media videos help patients to know about the therapeutic techniques. With the help of such informative learning resources, people can know about advanced biomedical equipment and diagnostic techniques.
