POSITIVE CHRONOTROPISM Meaning and Definition

1. Positive chronotropism is a physiological condition characterized by an increased heart rate. It refers to the ability of various substances or conditions to stimulate the heart and accelerate its rate of contraction. Chronotropism specifically refers to the regulation of heart rate, while positive chronotropism describes the augmentation of heart rate.

   When positive chronotropism occurs, the heart beats at a faster pace due to certain factors. These factors may include the release of hormones like adrenaline, sympathetic nerve stimulation, or the presence of specific drugs or chemicals that enhance cardiac activity. Positive chronotropism can also be influenced by factors such as exercise, stress, or emotional excitement.

   The acceleration of heart rate as a result of positive chronotropism is a natural response of the body to certain situations. It increases blood flow and oxygen supply, providing the necessary energy for the body to cope with increased demands. This mechanism is vital during physical exertion or stressful situations as it prepares the body to respond effectively.

   Positive chronotropism can be beneficial in maintaining cardiovascular health. However, excessive or prolonged positive chronotropic responses may indicate an underlying medical condition. It can be seen in conditions such as myocardial infarction, heart failure, or certain types of arrhythmias. Monitoring heart rate, especially in individuals at high risk of cardiac complications, is crucial to detect abnormal chronotropic responses and provide appropriate medical intervention.

2. Acceleration of the movement.

Etymology of POSITIVE CHRONOTROPISM

The word "positive chronotropism" is derived from two roots: "chrono-" and "-tropism".

1. "Chrono-" is derived from the Greek word "khronos", which means time. It is often used as a prefix to indicate time-related concepts in various scientific terms.

2. "-Tropism" comes from the Greek word "tropos", which means turning or change. In biology, "-tropism" refers to the movement or response of an organism or cells towards or away from a particular stimulus.

Therefore, "positive chronotropism" can be understood as the phenomenon where there is a positive or increased response or movement of an organism or cells in relation to time, particularly in the context of heart rate regulation.
