Abstract Cardiac activity responds dynamically to metabolic demands and neural regulation. However, little is known about this process during pregnancy. Reports show occasional fetal–maternal heart rate couplings, but it has remained unclear whether these couplings extend to more complex oscillatory patterns of the heart rhythm.

Overestimated Myocardial Ischemia
We introduced a case of a 69‐year‐old female patient with mitral valve prolapse with severe regurgitation. Postoperative routine ECG examination showed that the precordial leads were affected by the apical pulsation, leading to pseudo‐ST segment depression and a prolonged QT interval.

We describe supernormal conduction in a pattern of bigeminy or trigeminy due to serendipitous programming of the ventricular pacing rate at an exact factorial of the atrial flutter rate in a patient who underwent an ablate‐and‐pace strategy for recalcitrant atypical atrial flutter.

The LCX is the most prevalent culprit vessel with acute complete occlusion in NSTEMI patients, yet it has little effect on clinical outcomes. This subset of patients may be predicted by STV5 + STV6 ≥ 2.5 mm and T‐wave imbalance. ABSTRACT Background Complete blockage of the culprit coronary artery is associated with 30% of NSTEMI (non‐ST‐segment ...

A Narrow QRS Tachycardia With Alternating R‐R Interval
Lead II with a ladder diagram showing AVRT with alternating AV conduction via a fast and a slow nodal pathway. ABSTRACT We report a case of a 21‐year‐old female manifesting narrow QRS complex tachycardia and alternating R‐R intervals. The fixed RP interval suggested ventriculoatrial conduction via an accessory pathway (AP). The alternating PR intervals

Left Bundle Branch Pacing in a Patient With Dextroposed Heart: A Case Report
ABSTRACT The Right Ventricular (RV) apex has been the standard site for pacing in symptomatic bradyarrhythmias, but chronic RV pacing can cause adverse effects such as atrial arrhythmias and left ventricular dysfunction. Physiological pacing, including His bundle and left bundle pacing, offers alternatives with fewer complications. We present a 66‐year‐
