What is a Dangerous Heart Rate?
Before engaging in vigorous exercise, it is crucial to understand the maximum heart rate. The maximum heart rate varies with age. One calculates it by subtracting the age of a person from 220. Going beyond the maximum heart rate is not healthy. For example, if someone’s maximum heart rate is 185 bpm, exceeding 200 bpm during exercise is dangerous.
Target Heart Rate Zone
The target heart rate zone, which indicates the appropriate intensity for exercise, is typically 60-80% of the maximum heart rate. Consult the doctor before starting strenuous exercise, especially if someone has underlying health conditions.
High Resting Heart Rates
A resting heart rate of 120 bpm is considered high and could be a sign of anxiety. Regular monitoring can help detect dangerous changes in heart rate. High resting heart rates, such as 120 bpm, may signal underlying issues and should be monitored regularly for potential health concerns.
Summary
Understanding your maximum heart rate is essential before engaging in vigorous exercise. This rate varies with age, and one calculates it by สมัคร ufabet กับเรา รับโบนัสทันที subtracting a person’s age from 220. Exceeding the maximum heart rate, for example, surpassing 200 bpm when it’s 185 bpm, can be dangerous. The target heart rate zone, typically 60-80% of the maximum heart rate, indicates the ideal exercise intensity.
High Heart Rates (Tachycardia)
Tachycardia refers to having a heart rate above 100 bpm. It can be dangerous in some cases, as it disrupts the heart’s normal rhythm, reducing cardiac output and blood pressure levels. It can lead to organ damage, particularly in sensitive tissues like brain cells that require a constant supply of oxygen.
Types of Tachycardia
There are different types of tachycardia, and it is essential to understand their origins and implications. Here are some common types:
Atrial Fibrillation
It is the most common type of tachycardia, characterised by irregular electrical pulses in the heart’s upper chambers (atria). It carries a higher risk of blood clot formation and stroke.
Supraventricular Tachycardia (SVT)
SVT is a fast heartbeat originating in the heart’s upper chambers. It may be present at birth and relates to abnormal circuitry.
Atrial Flutter
This tachycardia results from irregular circuitry in the atria, leading to rapid and weak cardiac contractions.
Ventricular Tachycardia (VT)
VT occurs when the heart’s lower chambers beat quickly, often more severe than SVT.
Ventricular Fibrillation
In this condition, the ventricles receive rapid, uncoordinated electrical pulses, causing them to twitch instead of pumping blood. It requires immediate medical attention.
