The term is derived from the Greek tachy (fast) and cardia (heart) and is usually defined as a heart rate faster then 100 beats per minute.
Its significance is usually mainly as a sign that something else may be wrong and is only rarely dangerous in and of itself. Times when it can be dangerous include when the ventricles are contracting so fast that they do not have time to fill and pump effectively, and when the resulting increased oxygen demand causes some parts of the heart to not get enough oxygen, resulting in injury to the muscle tissue.
The commonly accepted definition of tachycardia as being above 100 beats per minute was selected by cardiologists in order to make it easier and faster for them to label EKG's in the days before computers calculated the heart rate for them, rather than being based on any study of "normals". Based on modern studies the normal upper limit for resting heart rate is probably closer to 90.
"Relative tachycardia" is when the heart rate is too high considering some circumstance.

What sinus rhythm has a rate of more than 100 beats per minute?
That's normal for hedgehogs...
Why is it important for one's heart rate to return back to a resting heart rate fast after exercise?
You would have sinus tachycardia a condition where less blood is pumped around the body by the heart For more info google sinus tachycardia
What is a Supraventricular event?
A supraventricular tachycardia is tachycardia (heart rate > 100) that originates above the AV node, in the atria. There are several different forms of supraventricular tachycardia, including sinus tachycardia, atrial fibrillation, atrial flutter, atrial tachycardia, multifocal atrial tachycardia, and a nebulous condition called paroxysmal supraventricular tachycardia (PSVT). Many people also consider junctional tachycardia a supraventricular tachycardia.
What is an unormal heart rate?
A heart rate that is over one hundred beats per minute is called tachycardia. There are several types of tachycardia, but the most common and least dangerous one is sinus tach. If you really wanted to get more information on this you should try doing some research on SVT (supra-ventricular tachycardia), and ventricular tachycardia.
Is Paroxysmal tachycardia the same as unsustained tachycardia?
No, it is not Paroxysmal tachycardia gives you the ability to watch the ``coming and going`` of tachycardia. Unsustained tachycardia has little to no change in rhythm rate.
Can you have normal sinus rhythm and sinus tachycardia simultaneously?
no
What is the difference between sinus tachycardia and inappropriate sinus tachycardia?
Inappropriate sinus tachycardia is a rapid heart rate at rest. The heart rate is more than 100 BPM. If the heart rate is more than 100 BPM less blood fills the coronary arteries so the less energy the heart has. Inappropriate sinus tachycardia needs treatment if the heart rate does not slow down with rest. It is only really a problem at rest. Sinus tachycardia is similar to Inappropriate sinus tachycardia. Sinus tachycardia is where the heart rate goes more than 100 BPM. It is normal for it to occur during excerise. Its only at rest it is classed as Inappropriate sinus tachycardia. How it can happen: 1) ST = sinus tachycardia is caused by increased sympathetic imput to the hearts pacemakers. The rythme of the heart is even and regular. Physical activity, Electric shock ( Inappropriate sinus tachycardia or sometimes V-fibb) Drugs These are things that can increases heart rate
Can sinus tachycardia be treated completely?
ST is treatable.
What are the key differences between atrial fibrillation and sinus tachycardia?
Atrial fibrillation is an irregular and often rapid heart rate that originates in the upper chambers of the heart, while sinus tachycardia is a regular but fast heart rate that starts in the sinus node. Atrial fibrillation can lead to blood clots and other complications, while sinus tachycardia is usually a normal response to stress or exercise.
What are the symptoms of sinus tachycardia?
Known more commonly as sinus tach, the condition known as sinus tachycardia causes elevated heart rate. Typically symptoms include general pain, fever, anxiety, dehydration, and can be as serious as sepsis and electric shock.
What sinus rhythm has a rate of more than 100 beats per minute?
That's normal for hedgehogs...
Can adenosine slow sinus tachycardia?
Yes, adenosine can slow sinus tachycardia by blocking AV nodal conduction. It works by activating adenosine receptors in the heart, which leads to hyperpolarization of the cardiac cells and ultimately slowing down the heart rate.

What does the medical abbreviation ST mean?
STS can mean serologic tests for syphilis.
What is a Supraventricular event?
A supraventricular tachycardia is tachycardia (heart rate > 100) that originates above the AV node, in the atria. There are several different forms of supraventricular tachycardia, including sinus tachycardia, atrial fibrillation, atrial flutter, atrial tachycardia, multifocal atrial tachycardia, and a nebulous condition called paroxysmal supraventricular tachycardia (PSVT). Many people also consider junctional tachycardia a supraventricular tachycardia.
What are the different heart rhythms a paramedic would analyze?
Sinus Bradycardia Sinus Tachycardia Sinus Dysrhythmia Sinus Arrest Wondering Pacemaker Premature Atrial Complex Paroxysmal Supraventricular Tachycardia Atrial Flutter Atrial Fibrillation Premature Junctional Complex Junctional Escape Complexes or Rhythms Accelerated Junctional Rhythm Ventricular Escape Complexes or Rhythms Premature Ventricular Complex Ventricular Tachycardia (VT) Ventricular Fibrillation (VF) Asystole Artificial Pacemaker Rhythms First Degree AV Block Second Degree AV Block Type 1 (Wenckebach) Second Degree AV Block Type 2 Third Degree AV Block Disturbances of Ventricular Conduction Pulseless Electrical Activity (PEA) Preexcitation Syndrome: Wolff-Parkinson-White Syndrome Broad complex tachycardia Narrow complex tachycardia
What is a carotid sinus massage?
A carotid sinus massage is a technique used to stimulate the carotid sinus in the neck to slow down the heart rate. This can be helpful in situations such as superventricular tachycardia or to check for hypersensitivity of the carotid sinus reflex. It should only be done by healthcare professionals due to the risk of causing harm.
