Age-dependent sympathetic neural responses to ß1 selective beta-blockade in untreated hypertension-related tachycardia

open access: yesBlood Pressure, 2018
Background: Elevated heart rate (HR) increases cardiovascular morbidity and mortality in hypertension. The impact of beta-blockers on patient prognosis in hypertension is controversial.

Tachycardia: The hidden cardiovascular risk factor in uncomplicated arterial hypertension

open access: yesCardiology Journal, 2020
Early detection and management of elevated blood pressure is crucial in reducing the burden of cardiovascular disease (CVD). The importance of an absolute risk assessment and patient risk stratification has been highlighted in the European hypertension ...

Tissue Tracking Imaging for Identifying the Origin of Idiopathic Ventricular Arrhythmias: A New Role of Cardiac Ultrasound in Electrophysiology [PDF]

open access: yes, 2005
Several strategies for mapping ventricular outflow tract tachycardia have been reported as useful indices for differentiating between those originating from the right and the left side.

Using skewness and the first-digit phenomenon to identify dynamical transitions in cardiac models [PDF]

open access: yes, 2016
Disruptions in the normal rhythmic functioning of the heart, termed as arrhythmia, often result from qualitative changes in the excitation dynamics of the organ.

Concept of the five ′A′s for treating emergency arrhythmias

open access: yesJournal of Emergencies, Trauma and Shock, 2010
Cardiac rhythm disturbances such as bradycardia (heart rate < 50/min) and tachycardia (heart rate > 100/min) require rapid therapeutic intervention.

Detection of Salinity by the Lobster, Homarus americanus [PDF]

open access: yes, 2001
Changes in the heart rates of lobsters (Homarus americanus) were used as an indicator that the animals were capable of sensing a reduction in the salinity of the ambient seawater.

Interaction of hypothalamic GABA\u3csub\u3eA\u3c/sub\u3e and excitatory amino acid receptors controlling heart rate in rats [PDF]

open access: yes, 1991
We have previously shown that microinjection of drugs that impair gamma-aminobutyric acid (GABA)-mediated synaptic inhibition into the dorsomedial hypothalamus (DMH) of rats generates cardiovascular and behavioral changes that mimic the response to ...

Influence of Atrioventricular Nodal Reentrant Tachycardia Ablation on Right to Left Inter-atrial Conduction [PDF]

open access: yes, 2005
Background: Radiofrequency (RF) catheter ablation is the procedure of choice for the potential cure of atrioventricular nodal reentrant tachycardia (AVNRT) with high success rates.

Modeling cardiac rhythm and heart rate using BFO and DOLCE [PDF]

open access: yes, 2009
This paper presents an application ontology for modeling cardiac rhythm and its anomalies such as tachycardia and bradycardia. We use BFO and DOLCE as ontological reference framework in order to compare their impact on ontology design.
