(1) Irregularities of cardiac rhythm indicate damage to the heart.

(2) Wo-Pa-Huai syndrome and ectopic cardiac rhythm of copulatory zone premature beat.

(3) Atrial fibrillation is the most common disorder of cardiac rhythm.

(4) The figure of infarction in the intrinsic cardiac rhythm was the same as in patients without pacemaker.

(5) The automated external defibrillator have functions of cardiac rhythm analysis system and shock advisory system.

(6) The sad truth about a true cardiac arrest is that drugs cannot help because there is no cardiac rhythm for them to stimulate. Sentencedict.com

(7) Results By corresponding treatment, the patients all recovered normal cardiac rhythm.

(8) There are many indexes, each with their different characteristics, for identifying cardiac rhythm, which can be used for the early diagnosis and risk prediction of cardiovascular disease.

(9) The numerical method is used to study the influence of action potential of cardiac tissue on cardiac rhythm.

(10) It is hard to define the exact time from arrest to arrival at the hospital, but the initial cardiac rhythm was mostly asystole .

(11) Transferred to the heart can occur such as chest tightness, palpitations or shortness of breath, syncope, cardiac rhythm disturbances and other symptoms.

(12) Methods Polysomnography had been performed on 66 patients with OSAS. the changes of nocturnal cardiac rhythm were observed, and compared before and after operation.

(13) This study described the quantitative simulation of exciting conduction velocity affection on cardiac rhythm with three dimensions realistic torso-heart geometry models.

(14) Palpitations can occur in disorders such as aortic regurgitation or thyrotoxicosis ; the most common cause is abnormal cardiac rhythm.

(15) Objective To study the effect of obstructive sleep apnea syndrome ( OSAS ) on cardiac rhythm during sleep.

(16) The numerical results show that the ring targets or spiral waves generated by cardiac action potential affect the cardiac rhythm greatly.

(17) A pacemaker sends electrical impulses to the heart to speed up or slow cardiac rhythm.

(18) Spectrograms of R-R intervals were processed and total spectral mass calculated. Analysis of heart rates by means of R-R interval spectral analysis can reflect the characteristics of cardiac rhythm.

(19) The factors influencing the image quality include the heart rate, the cardiac rhythm, the respiratory movement of patients and the trigger delays of imaging processing.

(20) Methods: Polysomnography has been performed on 66 patients with OSAS, the changes of nocturnal blood pressure and cardiac rhythm were observed.
