Twenty-four-hour ambulatory electrocardiographic examination was performed in 130 elderly patients (49 healthy, active subjects; 40 hypertensive without left ventricular hypertrophy; and 41 hypertensive with left ventricular hypertrophy). In the study group, mean age was 72.4 +/- 7.1 (sixty-five to eighty-eight) years. A significantly high prevalence of ventricular ectopic complexes was found both in hypertensive and in normotensive groups. According to the Lown grades, in grade 1, VPCs had very high prevalence in healthy subjects, in grade 2, VPCs had a high prevalence in hypertensives with left ventricular hypertrophy (73.5% and 48.8%, respectively). The results of this study demonstrate that ventricular premature complexes were common in hypertensive patients and healthy elderly but did not cause high complexity in either group. Ventricular premature complexes detected by ambulatory ECG monitoring in healthy, active subjects and in untreated hypertensive patients are not an independent risk factor in elderly patients.

Study Objectives: Evaluate the performance of the SANSA device to simultaneously assess obstructive sleep apnea (OSA) and cardiac arrhythmias.
Methods: Participants suspected or known to have OSA underwent polysomnography (PSG) while wearing SANSA. SANSA's algorithm was trained using 86 records and tested on 67 to evaluate training bias.

Objective: This study evaluated the safety and efficacy of isoproterenol administration as an adjunct for achievement of target heart rate (HR) during dobutamine stress echocardiography (DSE).
Background: In DSE, optimal accuracy is achieved when a target HR of 85% of maximal predicted heart rate (MPHR) is attained. Although rarely studied, intravenous isoproterenol has been used as an adjunct therapy to dobutamine and atropine to increase chronotropic response during pharmacologic stress testing.

Extreme prematurity involves a series of complications that a multidisciplinary team should manage. Taking into account the risks related to premature newborns, such as maternal-fetal infections, intrauterine growth restriction, and certain comorbidities associated with young gestational age, our objective is to highlight the importance of a multidisciplinary team in approaching cases with an unfavorable prognosis. This is a case report of an extremely preterm newborn who came from a high-risk pregnancy and needed long-term hospitalization in the Neonatal Intensive Care Unit (NICU) and mechanical ventilation.

Background: The QRS axis of the electrocardiogram (ECG) is often considered in clinical practice, but its determination is frequently limited to a rough estimation, such as "normal", with left or right deviation, and superior or inferior in the case of premature ventricular complexes (PVCs). However, a more exact determination of the QRS axis may be warranted in certain scenarios, such as to determine the origin of PVCs more precisely, and is attainable by visual estimation using the hexaxial reference system.
Objectives: The aim of this study was to determine how well such an estimation of the QRS axis would correlate with the axis calculated by formulas.

This study investigated the correlation between quantitative echocardiographic characteristics within 3 days of birth and necrotizing enterocolitis (NEC) and its severity in preterm infants. A retrospective study was conducted on 168 preterm infants with a gestational age of < 34 weeks. Patients were categorized into NEC and non-NEC groups.
