FUJI trial, we assessed the differences in electrocardiogram (ECG) parameters during RV pacing between a delivery catheter system and a stylet system and their associations with the lead tip positions. In this subanalysis of the Mt. The lead depth could have a more impact on the ECG parameters rather than the type of pacing lead.
In patients undergoing non-physiologic pacemaker (PM) implantation (eg, RV pacing), cardiomyopathy (CM) may develop - particularly in patients with an elevated pacing burden. In contrast to the current standard of upgrading the pacemaker only once CM develops, a strategy to predict CM before it actually develops would be advantageous.
In a world where technology reigns supreme, one of the most profound tools in medicine remains the irreplaceable electrocardiogram (ECG). Then, the current flows to an area known as the bundle of His, which divides into two branches (LBB and RBB) and is the only physiological pathway connecting the atria with the ventricles.
The autonomic nervous system (ANS) is critical to atrial fibrillation (AF) pathophysiology, but it is often difficult to differentiate vagal and adrenergic AF due to complex physiological interactions.1 2 We previously reported that ERPs were associated with increased susceptibility to AF.3
Electrocardiogram in clinic showed sinus arrhythmia with early repolarization and no ischemic changes. A 14-year-old male with no significant medical history presented with intermittent palpitations for 2–3 months that occurred at rest and were associated with light-headedness.
Introduction Electrocardiogram has been crucial in diagnosing and monitoring cardiovascular health for over a century. In 1887, a British physiologist, Augustus Waller, recorded the first human electrocardiogram using a capillary electrometer. However, back then, no one noticed his work.
and 0.64, respectively) with similar phenotypes.CONCLUSIONS:Long-term and acute responses to AF ablation reflect distinct clinical and electrical physiology, respectively. The external validation cohort showed similar results (area under the curve=0.81

Electromechanical association: a subtle electrocardiogram artifact. Electrocardiology 40: 475-477, 2007 ) — which is the BEST review I’ve seen on the physiology explaining the relative size of artifact deflections when the cause of the artifact is from a single extremity. Aslanger E, Yalin K. Journal of Electrocardiology. 2010.12.162.
A Deep Neural Network learning algorithm outperforms a conventional algorithm for emergency department electrocardiogram interpretation. This ECG comes from Pierre Taboulet ( [link] /)( [link] ) an ECG whiz who codes a lot of ECGs for Cardiologs' Artificial Intelligence Deep Neural Network algorithm ( [link] ). What an honor.
Traditional diagnostic tests like electrocardiograms (ECG) and stress tests may not always detect heart issues in women due to variations in their symptoms and heart physiology. Unique Challenges In Diagnosis Diagnosing heart disease in women poses unique challenges.
Essential Reading : Full text link: AHA/ACCF/HRS Recommendations for the Standardization and Interpretation of the Electrocardiogram, Part IV: The ST Segment, T and U Waves, and the QT Interval (full text link). Answer : you must treat the patient's underlying condition causing sinus tachycardia, and repeat the ECG at the lower heart rate.
Abnormal Electrocardiogram (ECG): Defined (San Fran syncope rule) as any new changes when compared to the last ECG or presence of non-sinus rhythm. Results : Electrocardiograms (99%), telemetry (95%), cardiac enzymes (95%), and head computed tomography (CT) (63%) were the most frequently obtained tests.
Innocent Heart Murmurs: These are also called functional or physiologic murmurs. Electrocardiogram (ECG): An ECG records the electrical activity of the heart and can help detect arrhythmias or other heart problems. Types of Heart Murmurs There are two primary types of heart murmurs: innocent heart murmurs and abnormal heart murmurs.
