normal sinus rhythmの例文

• This often results in the restoration of normal sinus rhythm of the heart.
• Hence, these cells generate the normal sinus rhythm and are called pacemaker cells as they directly control the heart rate.
• Bachmann's bundle is, during normal sinus rhythm, the preferential path for electrical activation of the left atrium.
• RPDE values H _ { norm } for normal sinus rhythm ECG, and for ECG from a patient with sleep apnoea.
• As with other procedures off-bypass, the surgeon can confirm that AF corrects to normal sinus rhythm during the procedure.
• Often, for patients in normal sinus rhythm, there is also a lead in the right atrium to facilitate synchrony with the atrial contraction.
• "' Defibrillation "'is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation ( VF ) and normal sinus rhythm.
• Ventricular fibrillation ( VF ) could be returned to normal sinus rhythm in 60 % of cardiac arrest patients treated with a single shock from a monophasic defibrillator.
• An impulse ( action potential ) that originates from the SA node at a relative rate of 60-100bpm is known as " normal sinus rhythm ".
• Is it slight movements-the hand moving a bit while trying to measure at the wrist ? is it the different things that cause the waves in the heart's normal sinus rhythm?
• The goal is avoidance of infarction, heart failure, and / or lethal arrhythmias ( ventricular tachycardia, ventricular fibrillation, asystole, or pulseless electrical activity ), so ultimately to restore normal sinus rhythm.
• The M 2 muscarinic receptors are located in the heart, where they act to slow the heart rate down to normal sinus rhythm after positive stimulatory actions of the parasympathetic nervous system, by slowing the speed of depolarization.
• The normal treatments for episodes due to the pathological look-alikes are the same mainstays for any other episode of cardiac arrest : Cardiopulmonary resuscitation, defibrillation to restore normal sinus rhythm, and if initial defibrillation fails, administration of intravenous epinephrine or amiodarone.
• A common example would be an " interpolated PVC " ( a type of premature ventricular contraction ) during normal sinus rhythm; the PVC does not cause an atrial contraction, because the retrograde impulse from the PVC does not completely penetrate the AV node.
• Antiarrhythmic agents that exhibit reverse use-dependence are more efficacious at preventing a tachyarrhythmia than converting someone into normal sinus rhythm . " Because of the reverse use-dependence of class III agents, at low heart rates class III antiarrhythmic agents may paradoxically be more arrhythmogenic ."
• Abnormalities in the normal sinus rhythm of the heart can prevent the heart from effectively pumping blood, and are generally identified by ECG . These cardiac arrhythmias can cause an abnormal but regular heart rhythm, such as a rapid heart rate ( tachycardia, classified as Wolff-Parkinson-White syndrome.
• When an individual is in normal sinus rhythm, the ECG characteristics of WPW are a short PR interval ( less than 120 milliseconds in duration ), widened QRS complex ( greater than 120 milliseconds in duration ) with slurred upstroke of the QRS complex, and secondary repolarization changes ( reflected in ST segment-T wave changes ).
• The term "'normal sinus rhythm "'( "'NSR "') is sometimes used to denote a specific type of sinus rhythm where all other measurements on the ECG also fall within designated normal limits, giving rise to the characteristic appearance of the ECG when the electrical conduction system of the heart is functioning normally.
• While procainamide and quinidine may be used in the conversion of atrial fibrillation to normal sinus rhythm, they should only be used in conjunction with an AV node blocking agent such as digoxin or verapamil, or a beta blocker ), because procainamide and quinidine can increase the conduction through the AV node and may cause 1 : 1 conduction of atrial fibrillation, causing an increase in the ventricular rate.
