What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
Does the atrial rate equal the ventricular rate in the ECG tracing?
yes
What are the ECG characteristics of Atrial flutter?
1- Inverted P waves (F waves) in II, III and AVF. 2- saw-tooth pattern between QRS complexes in II,III and AVF. 3- Atrial rate is 250-400 and regular but ventricular rate depends on AV node and between 60-150 and typically regular. 4- QRS is not wide 5- T waves not identifiable.
What type of disease can be find by heart beat?
If you hear a heart mumur, this indicates heart valve disease. If the heart rate is irregular it is either atrial fibrillation or ectopic beats, either atrial or ventricular.
Do the ventricles have the same rate as the atria in atrial fibrillation?
No. In atrial fibrillation, the atria have regional depolarizations at a rate of over 300 per minute. Fortunately, the atrioventricular node prevents the ventricular rate from being this high as we would die from lack of cardiac output. There are conditions where the ventricles are depolarized at a rate approximating the atrial depolarization - these include the Lown-Ganong-Levine and Wolff-Parkinson-White syndromes, and consist of abnormal tracts between the atria and ventricles around the AV node.
What is the difference between ventricular fibrillation and arrhythmia?
Ventricular fibrillation (V fib, VF) is a fatal dysrhythmia that occurs as a result of multiple weak ectopic foci in the ventricles. In other words, there is NO coordinated atrial or ventricular contraction and NO palpable pulse. Ventricular tachycardia (VT or V tach) have three or more PVCs with a rate of >100
Should emergency defibrillators be used on patients suffering atrial fibrillation attacks?
If patients with atrial fibrillation experience rapid heart rate (rapid ventricular response) and are hemodynamically unstable (hypotension, altered mental status) then electrical cardioversion is appropriate. Defibrillation is never utilized in atrial fibrillation.
Difference between atrial fibrillation and atrial flutter?
They're he same thing. Atrial flutter is more of a slang term, and is sometimes found in patients with atrial tachycardia. Basically, atrial fibrillation is a disorder, and atrial flutter is a symptom
What does arrhythmia mean?
A condition in which the heart beats with an irregular or abnormal rhythm. Could be PVCs (Premature Ventricular Contractions), slow heart rate (<60 bpm = bradycardia), fast heart rate (>100 bpm = tachycardia), atrial fibrillation, and more
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is sinus rhythm with occasional venticular ectopics?
What could the prognosis be with a women in her late 40s with underlyning sinus rhythm, mixed with VEBs and AEBs? average rate of 57bpm ( range 37-143bpm) Heart rate less than 50bpm were noted 57% but with no pauses greater than 2 seconds. with sinus bradycardia, rate 52bpm and ventricular premature beat? women doesnt smoke, drink or take drugs of any kind. thank you
Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant
