What else can I help you with?
Why does tachycardia greater than 200 beats per minutes results in decreased coronary perfusion?
The heart does not have enough time between contractions to fill with enough blood to maintain adequate cardiac output. This is especially a concern because the heart itself is perfused during diastole (the period between ventricular contractions).
What is the relation between the tachycardia and tachypnea?
Tachycardia is an increase in heart rate while tachypnea is an increase in the rate of breathing
What is the Difference between junctional tachycardia and accelerated junctional rhythm?
An accelerated junctional rhythm has a heart rate between 60 and 100. Meanwhile, a junctional tachycardia has a heart rate >100.
What are the differences between isometric, concentric, and eccentric muscle contractions?
Isometric muscle contractions happen when the muscle stays the same length, concentric contractions occur when the muscle shortens, and eccentric contractions occur when the muscle lengthens.
How you do labor watch?
time the seconds in between her contractions
What are the differences between tonic and phasic muscle contractions in terms of their duration and intensity?
Tonic muscle contractions are sustained and steady, while phasic muscle contractions are brief and intense. Tonic contractions last longer and have a lower intensity, while phasic contractions are shorter in duration but have a higher intensity.
What is the difference between supra ventricular tachycardia and paroxysmal supra ventricular tachycardia?
PSVT are those SVTs which are sudden, abrupt, almost immediate and unexpected onset and are more regular as well... PSVT is just the type of SVT..
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
What is blood pressure that remains between heart contractions?
diastolic pressure
What is the difference between palpitation and tachycardia?
Palpitation is feeling ones own heart beat. The heart rate can be normal, increased or even reduced. Tachycardia on the other hand is increased heart rate. It may or may not be associated with palpitation. Heart rate above 100 beats per min is tachycardia
What is the difference between tachycardia and bradycardia?
Normal heart beat rate is 60-100 bpm, In basic terms, we call it bradycardia when the heart rate is below 60 bpm, whereas tachycardia is when it exceeds 100 bpm.
What is the definition of contractions?
