Why is it only possible to induce an extrasystole during relaxation?
It is only possible to induce an extrasystole during relaxation because the heart needs to be in a certain phase of the cardiac cycle for an extra beat to occur. During relaxation (diastole), the heart muscles are more excitable, making it easier for an extra electrical impulse to trigger a premature contraction. This is why inducing an extrasystole during relaxation is more likely to succeed than during contraction (systole).
Why is it only possible to induce an extrasystole during relaxation period?
The cardiac muscle is incapable of reacting to any stimulus before approximately in the middle of phase 3. It will not react to a normal cardiac stimulus before phase 4.
What is a premature ventricular contraction is classified as a?
extrasystole.
Is it possible to induce a specific type of dream?
Yes, it is called Lucid Dreaming and it can be learned.
Is it possible for thermophilic organisms to induce infections in warmblooded animals?
Is it possible for thermophilic prganisms to induce infections in warm blooded animals
How do you self induce amnesia?
I am sure that it would be possible to induce amnesia by means of brain surgery, however, that would be horribly unethical.
During which portion of the cardiac cycle is it possible to induce extra systole?
Extrasystole is an extra ventricular systole that happens during the begging of relaxation (repolarization). Since the cardiac is able to depolarize only after repolarization, any stimulus upon the repolarization period created an increased ventricular contraction or which is also called extrasystole but not a new contraction.
Is it possible to induce your period?
Take a knife...............and stab repeatedly.
Is cytotec efffective to induce pregnancy?
In the right dose it can induce miscarriage, yes, not pregnancy.
Can cold induce headaches?
Yes.
Is it possible for a woman to induce lactation with pierced nipples?
yes it is possible I had mine done for a few years before I had my son and breastfed him just male sure u take em out while doing it
What is the cause of compensatory pause after an extrasystole?
Extrasystole is due to the irregular contraction of the ventricle before the atria. When this happens, an action potential is elicited and the ventricle contracts. The action potential had a refractory period, during which the intrinsic heart rate attempts to fire but cannot elicit a contraction. This is why extrasystole is often referred to as skipping a beat. The compensatory pause is the time it takes for the beat to resume normal contraction.
