Regulation of Cardiomyocyte Mechanotransduction by the Cardiac Cycle [PDF]

open access: bronzeCirculation, 2001
Background —Overloading the left ventricle in systole (pressure overload) is associated with a distinct morphological response compared with overload in diastole (volume overload). Methods and Results —We designed a novel computer-controlled experimental system that interfaces ...

The diastolic duration as a percentage of the cardiac cycle in healthy adults: A pilot study [PDF]

open access: yesIndian Heart Journal
Background: A widely accepted concept in cardiovascular physiology states that diastole constitutes 62.5 % of the cardiac cycle during a typical 0.8-s cycle at 75 beats per minute.

A puzzle used to teach the cardiac cycle [PDF]

open access: yesAdvances in Physiology Education, 2015
The aim of the present article is to describe a puzzle developed for use in teaching cardiac physiology classes. The puzzle presents figures of phases of the cardiac cycle and a table with five columns: phases of cardiac cycle, atrial state, ventricular state, state of atrioventricular valves, and pulmonary and aortic valves. Chips are provided for use

Relationships between irregular pulsation and variations in morphological characteristics during the cardiac cycle in unruptured intracranial aneurysms by 4D-CTA [PDF]

open access: yesFrontiers in Neurology
Background and purposeIrregular pulsation of the aneurysmal wall has been suggested as a novel predictor for aneurysm rupture. Aneurysm volume variations during the cardiac cycle and the association between irregular pulsation and morphological features ...

The Variation in the Diastolic Period with Interventricular Septal Displacement and Its Relation to the Right Ventricular Function in Pulmonary Hypertension: A Preliminary Cardiac Magnetic Resonance Study

open access: yesDiagnostics, 2022
Background: Pulmonary hypertension (PH) is known to alter the biventricular shape and temporal phases of the cardiac cycle. The presence of interventricular septal (IVS) displacement has been associated with the severity of PH.

Synchronization of Wave Flows of Arterial and Venous Blood and Phases of the Cardiac Cycle with the Structure of the Peripheral Pulse Wave in Norm: Part 2 [PDF]

open access: yesInternational Journal of Biomedicine, 2018
Hemodynamic indices studied in practically healthy people were obtained by catheterization in various vascular areas: the chambers of the heart (ventricles, atria, coronary sinus), pulmonary trunk, aorta, inferior vena cava, superior vena cava, right ...

Application of In Silico Trials for the Investigation of Drug Effects on Cardiomyopathy-Diseased Heart Cycle Properties

open access: yesApplied Sciences, 2023
In this paper, we present the abilities of an in silico platform used to simulate the effects of different drugs on heartbeat cycle performance. The platform is based on a finite element modelling approach with the fluid–solid interaction implemented ...
