“…It has been reported that P max and PD are associated with age, 28 left ventricular systolic function, 29 left atrium size 30 and increased sympathetic activity. 31 In our study there was no significant difference between the two groups in terms of these measures.…”

Effect of Ongoing Inflammation in Rheumatoid Arthritis on P-Wave Dispersion

et al. 2007

It has been emphasized recently that there is a strong association between atrial fibrillation and inflammation. Rheumatoid arthritis (RA), characterized by ongoing inflammatory activity, can increase the risk of atrial arrhythmia. P-wave dispersion has been encountered as a risk factor for atrial fibrillation and the effect of inflammation on P-wave dispersion has not been studied thoroughly. The aim of this study was to examine the effect of ongoing inflammatory activity in RA on P-wave dispersion. The study comprised 82 patients diagnosed with RA and 41 healthy volunteers as controls. Systolic functions of all participants were evaluated by echocardiography. Maximum P-wave duration and dispersion were calculated and found to be significantly increased in the RA group compared with the healthy controls. These parameters were also significantly correlated with C-reactive protein levels. The findings of this study suggest that RA may be associated with increases in P-wave dispersion and maximum P-wave duration, and that this association may result from ongoing inflammation.

“…Cheema et al (22) reported that epinephrine and norepinephrine extended the maximum period of P wave. It was reported by Tukek et al (23) that, the increase in sympathetic activity causes increasing in P dispersion. The P wave of the electrocardiogram may show alterations that can be associated with atrial arrhythmias (6) .…”

OBJECTIVE:The purpose of this study is to examine the electrocardiographic features of patient stung by scorpions. METHODS:Seventy six patients stung by scorpions were gathered in the study. 12 lead derivations electrocardiography (ECGs) was performed to all patients. The ECG which were performed when the patients had maximum (grade 3) pain were obtained for determination. The determined parameters were: PR segment and QRS duration, QTmin, QTmax, QTc, QT dispersion (QTd) intervals, minimum P wave duration (PWmin), maximum P wave duration (PWmax) and P wave dispersion (PWd). RESULTS:Seventh six patients (37 males and 39 females, mean age: 33,7±14,7 years) were included in this analysis. Heart rate, QRS duration, QTc, QTd, PWmin, and PWd which we found were 84,5±13,8 beat/min, 98,8±11,8 msn, 412±27,4 msn, 412±27,4 msn, 412±27,4msn and 41,4±19,7 msn respectively. CONCLUSION: Scorpion sting lead electrocardiografic variability. The most common changes were ST changes, sinus tachycardia, atrial ectopic beat, bradycardia, and ventricular ectopic beat.

“…The speed of the impulse conduction in the myocardium depends on the activity of the immune system and the presence of ischaemia (4,6). Additional factors that can increase P d and that should be taken into account while interpreting results related with atrial conduction include endocrine disease, such as diabetes, thyroid hyperfunction, and the terminal stadium of renal failure (2,5,10,(21)(22)(23)25). In people, changes of Pwave dispersion were also observed during changes in the tension of the autonomic nervous system, for example while conducting the Valsalva maneuver (1) or in connection with panic attacks (24).…”

Electrocardiographic examinations were performed on 45 Silesian breed horses (group K, 3-16-year-old, 16 stallions, 29 mares) and on 25 Polish Primitive breed horses (group P, 1.5-19-year-old, two stallions, six geldings, 17 mares). Einthoven and chest leads were used. P-wave dispersion was electronically evaluated. There was no correlation between P-wave dispersion and other ECG parameters, age, sex, body mass, or month of pregnancy. The average value of P-wave dispersion for all horses was 30.77 ms (SD 3.92 ms), however in particular groups it was: in group P -31.89 ms (SD 3.07 ms), and in group K -30.15 ms (SD 4.27 ms). The maximum value of P-wave dispersion in the studied population was 40 ms, in groups P and K -37,6 ms and 40 ms, respectively. The physiological value of P-wave dispersion for the group of horses was below 45 ms.
