Relationship between ecg and pulse

relationship between ecg and pulse

Difference Between Heart Rate and Pulse from the thorax with the transmitter of heart rate monitor or the electrodes of the electrocardiograph (EKG). Pulse is. Besides such clinical applications, psychophysiological studies highlighted the relationship between the Heart Rate variations and the human emotional. An electrocardiogram (ECG) is the recording of the sum of the electrical Diagram of the propagation and regression of electrical excitation in the heart in relation to The ECG reading, heart rate and blood pressure are continuously monitored Among others, it can be used to diagnose anterior, lateral and posterior wall.

In order to do this, the heart muscle must contract, which requires an electrical impulse.

The electrical current is then transmitted via specific pathways throughout the heart, enabling regular contraction and relaxation. This electrical current can be detected on the surface of the body i.

Pathway of the electrical impulse: From the sinus node, the electrical impulse starts by spreading throughout the atria from right to left.

When this happens, the cells lose their internal negativity, a process known as depolarization. The depolarization of the atria causes them to contract. The electrical current then spreads to the atrioventricular node AV nodefrom where it is further transmitted to the intraventricular Septum separates the left and right ventricles.

In order to depolarize the ventricles, the electrical impulse travels through the bundle of His, along the right and left bundle branches from left to rightand ends at the Purkinje fibers. This process causes depolarization of the ventricles, causing them to contract. While the ventricles are being depolarized, the atria are regaining their internal electrical negativity, a process known as repolarization.

This allows them to relax. Once the ventricles have fully depolarized, they too become repolarized, and which point they relax as well.

The heart's conduction system Update your cardiac diagnostics You can record a clinical lead ECG using just 4 electrodes and an app on your iPad or iPhone. Learn more The entire process of depolarization and repolarization is depicted on the ECG. The individual events are represented as spikes and waves, each representing a specific part of the cardiac conduction cycle.

The picture below shows the pathway of an electrical impulse as it corresponds to the spikes and waves on an ECG. To do this, the heart is shown on its side. A heart beat is the sounds of the heart valves opening and closing in response to pressure differences.

Heart rate vs. pulse: Are they the same or different?

During each heart beat blood is pushed throughout the body, augmenting blood pressure and therefore the pulse rate in the main arteries. Pulse rate is the measure palpable blood pressure increases throughout the body that occurs with each heartbeat. Pulse rate is basically the physical sensation of a heart beat felt through the arterial vascular system.

Pulse can be measured from the earlobe with a pulse meter known as a Photo Reflectance or Infrared Sensor Monitor. Your pulse can vary with body movements and should, therefore, be measured while at rest. An easy way to measure pulse rate is to place your fingers at the base of the thumb at the wrist, or at the neck, just next to your windpipe.

Heart rate vs pulse rate: The difference The cardiovascular system is a complex network of specialized muscle and tissue.

Heart rate vs. pulse: Are they the same or different?

They all work together to ensure that oxygen-rich blood is being supplied to the far reaches of the human body. No organ is more important than the brain, which is why when our blood pressure becomes too low we often collapse or faint so our head will be on a lower plane, horizontally on the floor with the rest of the body.

This is to circumvent the effects of gravity and help the heart pump blood to the brain more easily. Our heart rate and pulse rate are key factors to ensuring blood pressure is high enough to sustain the perfusion of blood to all organs of the human body.

While both are considered similar each represents a different mechanic of how the body is responding to differences in blood pressure. Under normal condition, both the heart rate and pulse rate tend to be the same, but in conditions that affect either only the heart or only the blood vessels, these values may differ.
