Non-St Elevation Myocardial Infarction Presentation In Severe Aortic Stenotic Patient, Margi Desai, Daniel Maysonet

The Journal of Integrated Primary Care

This case report demonstrates a patient who presents with typical findings for a diagnosis of NSTEMI. Upon further evaluation, this diagnosis was able to be ruled out. Presentations and labs consistent with NSTEMI masked the true diagnosis of aortic stenosis due to oxygen supply/demand mismatch.

Tp-E Interval, Tp-E/Qt, And Tp-E/Qtc Ratios In Patients With Primaryhyperparathyroidism And Their Relationship With Cardiac Arrhythmic Events, Yücel Yilmaz, Şaban Keleşoğlu, Ferhat Gökay, Yasi̇n Şi̇mşek

Turkish Journal of Medical Sciences

Background/aim: Primary hyperparathyroidism (PHPT) is an endocrine disorder characterized by hypercalcemia caused by excessive parathyroid hormone (PTH) secretion from the parathyroid gland. PHPT was previously shown to increase cardiac arrhythmias. Besides, new indices, such as the Tpeak-Tend (Tp-e) interval, Tp-e interval/QT interval (Tp-e/QT) ratio, and Tp-e interval/corrected QT interval (Tp-e/QTc) ratio may be associated with ventricular arrhythmias and sudden cardiac death. Therefore, we aimed to investigate the relationship between PHPT and the changes to Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio. Materials and methods: We carried out the study with 41 patients with PHPT and 40 control subjects. We calculated …

Ecg Measurement Parameters Of Athletes Are Reliable When Made With A Smartphone Based Ecg Device, Andrew Gilliland, Mark Timmons, Jeffrey K. Harris, Stephen M. Petrany, Terry A. Shepherd, Grant S. Buchanan, Nicole Decker, Charles Giangarra

Marshall Journal of Medicine

Pre-participation cardiac screening including electrocardiogram (ECG) is a subject of controversy among sports medicine practitioners. Opponents of pre-participation ECG screen site concerns regarding the cost and accuracy of the testing. Recently, a single lead ECG accessory has become available for use with smartphones. The purpose of this study was to evaluate the between and within rater validity and reliability of the Kardia device in recording the ECG parameters rate, rhythm, and PR, QRS, and QT intervals. The ECG parameter made with the smartphone were also compared to same measures made using a 12 lead electrocardiograph.

This investigation used a repeated …

Twenty-Four Hour Holter Monitoring In Finishing Cattle Housed Outdoors, D. A. Frese, J. D. Thomason, C. D. Reinhardt, S. J. Bartle, D. N. Rethorst, G. H. Loneragan, E. F. Schwandt, D. U. Thomson

Kansas Agricultural Experiment Station Research Reports

Ambulatory electrocardiogram monitoring, in the form of Holter monitoring, has been used in human and veterinary medicine for decades as an aid in the diagnosis and determination of appropriate therapy of heart rhythm disturbances. Within veterinary medicine, Holter monitors have been primarily used in companion animal species, yet little attention has been given to food animal species. Moreover, the heart rhythm in clinically normal cattle fed high concentrate diets and housed outdoors in confined drylot facilities has not been previously reported. In order to properly identify pathologic arrhythmias in cattle, the normal rhythm and arrhythmia prevalence in healthy cattle should …

Old Dog, New Tricks - Usefulness Of The Ecg In Monitoring Acute Rejection Post Cardiac Transplantation, Paul Anaya, Samy-Claude Elayi

The VAD Journal

Electrocardiographic abnormalities have been described in the setting of acute rejection following orthotopic cardiac transplantation. The following is a brief commentary related to an interesting case report by Goldraich et al. which was recently published in the VAD Journal.

Old School Still Has Merit: Ecg As A Marker Of Cardiac Recovery At Weaning From Mechanical Circulatory Support, Livia Adams Goldraich, Vivek Rao, Fillio Billia, Heather Joan Ross

The VAD Journal

In a case of acute cardiac allograft failure requiring temporary mechanical circulatory support (MCS), serial electrocardiograms (ECG) denoted the degree of myocardial inflammation and damage caused by severe rejection and subsequent recovery. This case highlights the relevance of the ECG during temporary MCS and suggests that resolution of acute electrocardiographic abnormalities might be a marker of myocardial recovery to help guide appropriate timing for weaning from MCS in the setting of acute graft failure.

Assessment Of Amiodarone Effects On Intact Cats' Electrocardiograms, Farzad Gouya, Ali Shabestari Asl

Turkish Journal of Veterinary & Animal Sciences

Amiodarone can be used for treatment of ventricular and supraventricular arrhythmias in canine medicine, but its exact role in feline electrocardiography and its side effects have not been proven. The aim of this study was the evaluation of amiodarone and its different dosages' effects on intact feline heart electrocardiograms. Eight healthy stray cats were selected and control electrocardiogram was obtained. Amiodarone tablets were prescribed twice daily at 10 mg/kg for 7 days. The same protocol was repeated with doses of 15 and 25 mg/kg. Hexagonal electrocardiograms were obtained at the end of each stage. Electrocardiograms were evaluated for P amplitude …

To investigate the improvement in electrocardiogram (ECG) interpreting skills after a standardized ECG interpreting program as a continuous medical education activity among primary care physicians. Materials and methods: The study was conducted in Turkey between December 2006 and October 2010. Out of the 81 provinces in Turkey, 17 were randomly selected and all physicians were invited to take the course on a voluntary basis and in total 798 physicians agreed to participate. The course was a half-day program. A test was applied to the participants before and after the training. The results of 781 participants were analyzed. Results: Of the …

The Effect Of Ration Supplemented With Zinc On Ecg In Broilers, Ali̇ Çinar, Nurcan Dönmez

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to evaluate the effects of ration supplemented with zinc on the electrocardiograms of 60 broiler chicks. The chicks were divided into four groups,one control and three experimental groups (II,III,IV). Zinc was given to the experimental groups at doses of 125, 500, 1000 mk/kg respectively, in their ration for 60 days.The electrocardiogram recordings were performed on chicks on the 60 th day of the experiment. Leads I, II, III, aVR, aVL and aVF were recorded in the electrocardiographs of the chicks.All electrocardiograms exhibited P, R, S and T waves but P wave generally interfered with the …

The Effects Of Carbon Tetrachloride (Ccl_4 ) Induced Experimental Acute And Chronicintoxication On Hystological Structure Of Liver And Some Hematological Values Andelectrocardiogram In Rabbits, Ali̇ Çinar, Meci̇t Yörük, İsmai̇l Meral, Di̇de Kiliçalp, Ahmet Koç, Ali̇ Erteki̇n

Turkish Journal of Veterinary & Animal Sciences

This paper reports an investigation of the effects of acute and chronic carbon tetrachloride intoxications on the histologic structure of the liver and hematological values and electrocardiograms in rabbits. The rabbits were divided into 3 groups of 7. The first group was the control group, the second group was acutely intoxicated and the third group was chronically intoxicated. In the acutely intoxicated group, caryorexsis, along with necrosis was observed in the hepatocyte of the centrolobular area of the liver. In the chronically intoxicated group, connective tissue mass around the V. centralis increased. This increase of connective tissue caused chirrosis. Hematological …

Turkish Journal of Veterinary & Animal Sciences

The present study was planned to investigate the effects of two different concentrations (10 and 40 mg/kg) of monensin, carboxylic ionophore antibiotic, on the ECG and the serum Na + and K + concentrations of rabbits. Fifteen male rabbits, about 2 kg and 1 year old, were used. ECGs were recorded by a direct writing electrocardiograph. Blood samples for measuring serum Na + and the K + concentrations were collected and the leads I, II, II, aVR, aVL and aVF were recorded before and 6 hours after monensin was given. The durations and amplitudes of waves on the trace were …

Reentry, Gordon Moe

MCV/Q, Medical College of Virginia Quarterly

There are two ways in which impulses can be generated: one is by the spontaneous discharge of a pacemaker cell in either the normal site or a subsidiary site, and the other is by reentry. The concept of reentry is a very old one postulated by clinical cardiologists many years before its demonstration.
