متن کاملUsing Blood Pressure Data to Detect Premature Ventricular Contraction Beat
In this paper we present an algorithm to detect premature ventricular contraction beats (PVCs) which based on blood pressure measuring data technique. A PVC beat is chosen and compared with the number of heart beats per unit time (Heart rate) using Mat lab. The heart rate may be too fast or too slow. PVC beats are then detected using a decision parameter which is a discrete function of two uneq...
متن کاملBeat Estimation on the Beat
This paper presents a novel method for the estimation of beat interval, and the exact location of the beats from audio files. As a first step, a feature extracted from the waveform is used to identify note onsets. The estimated note onsets are used as input to a beat induction algorithm, where the most probable beat intervals are found. The note onsets corresponding to the beat locations are th...
متن کاملChange of cardiac rhythm in the rabbit after an atrial premature beat.
In the isolated right atrium of the rabbit, premature beats were elicited by electrical stimulation. When the activation front of a premature beat did not reach the sinoatrial (S-A) node soon enough to discharge the pacemaker prematurely, the pause following the premature beat was compensatory. However, when the activation front forced the pacemaker to discharge prematurely, the premature beat ...
متن کاملParoxysmal atrioventricular block precipitated by an atrial premature beat. What is the mechanism?
A 65 year-old woman presented with two episodes of syncope. She developed paroxysmal atrioventricular (AV) block when an ECG was being recorded (Fig. 1). She developed at least one other similar episode. Then, she developed complete AV block with a stable escape ventricular rhythm of about 30 bpm during which an atrial premature beat was conducted (Fig. 2). Isoproterenol was administered which ...
