1. Nervous System controlling Heart Rate The heart rate is therefore determined by the balance between sympathetic and parasympathetic nerve activity The cardiovascular centre receives input from 4 main receptor groups, these inputs are processed and the sympathetic/ parasympathetic NS is recruited accordingly.

SINUS ARRHYTHMIA There is a change in HR seen during respiratory cycle in inspiration, there is increase in HR In expiration, there is decrease in HR It is commonly seen in children and young adults.

2. -Heart rate, or heart pulse, is the speed of the heartbeat measured by the number of poundings of the heart per unit of time — typically beats per minute (bpm). The heart rate can vary according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. Activities that can provoke change include physical.

Regulation of Heart Rate Uploaded by Tripat Singh Normocardia: defined as normal heart rate Range - 60 - 100 beats / min. average 70/min Bradycardia: defined as decrease in heart rate to less than 60 beats / min-in athletes.
Fetal Heart Rate Physiology and its control with EFM
Circulatory adjustments are effected by altering the output of the pump (the heart), changing the diameter of the resistance vessels (primarily the arterioles), or altering the amount of blood pooled in the capacitance vessels (the veins). Regulation of cardiac output is discussed in Chapter 30. This chapter reviews the systemic regulatory.

Whereas in hormonal regulation, hormones like catecholamine, acetylcholine regulates the heart rate. Other factors like environment stress, drugs also regulate the heartbeat. Cardio-vascular system is not only associated with circulation of blood, but also with certain CVDs like, heart attack, hypertension, cardiomypathy, congenital heart.

Intrinsic Regulation • Depolarization muscle membrane creates an action potential or electrical impulse • Impulse travels through the heart in an established pathway • SA node →across atria →AV node →AV bundle →left & right bundle branches → Purkinjie fibers → Ventricles

6. Maximum Heart Rate (MHR) - age related number of BPM of the heart when working at maximum MHR= 220 - Age Knowing this number along with RHR allows you to find the correct intensity for your body when being physically active. Low intensity, closer to RHR High intensity, closer to MHR Given this information, where do you think HR shou.

The body's nervous system, neurotransmitters and hormones regulate the sinus node and play a huge role in how the body regulates heart rate. Each contraction of the heart muscle regulates the flow of blood in the form of a pulse or heart rate. The pulse is measured in beats per minute. Emotional and physical stress, exercise and other physical.

Cardiac regulation is constantly working to ensure sufficient blood flow supply is sent around the body. When we exercise, we increase cardiac output so our muscles can get the oxygen they need. When we sleep, cardiac output is decreased as our body is resting. This section will explore the various regulated variables that influence cardiac.

There are two primary modes by which the blood volume pumped by the heart, at any given moment, is regulated: 1) intrinsic cardiac regulation, in response to changes in the volume of blood flowing into the heart; and 2) control of heart rate and cardiac contractility by the autonomic nervous system. The intrinsic ability of the heart to adapt.

Heart Rate and its Regulation (With Diagram) Article Shared by ADVERTISEMENTS: Normal heart rate is about 60-90 beats per minute. On an average, the rate at which the heart beats is about 75 per minute. It depends on the balanced activity between the sympathetic and parasympathetic nerve influence that are acting on it.

Answers • 1. You need a heart to pump blood. • 2. You need blood to circulate to all the parts of your body in order for oxygen to get to all body cells (gas exchange) • Oxygen/ Carbon Dioxide exchange Introduction • How does your heart pump blood?
Control of heart rate
The cardiac cycle is a normal activity of the human heart and is regulated automatically by the nodal tissues- the sinoatrial node (SA node) and atrioventricular node (AV node). The variation in the cardiac cycle results in an increase or decrease in cardiac output.
