Resumen
Two models of electrical conduction in the cardiac ventricles are considered. The first model considered is that of a strand of ventricular muscle which uses the one-dimensional cable equation with the Beeler-Reuter model to represent the transmembrane currents. The effect of periodic stimulation on the strand is numerically simulated, and it is found that as simulation frequency is increased, the rhythms of synchronization are successively encountered. It is shown that this sequence of rhythms can be accounted for by considering the response of the strand to premature stimulation. This involv

Resumen
Statistical data from clinical studies indicate that the death rate caused by heart disease has decreased due to an increased use of evidence-based medical therapies. This includes the use of magnetic resonance imaging (MRI), which is one of the most common non-invasive approaches in evidence-based health care research. In the current work, I present 3D Lagrangian strains and torsion in the left ventricle of healthy and isoproterenol-stimulated rats, which were investigated using Displacement ENcoding with Stimulated Echoes (DENSE) cardiac magnetic resonance (CMR) imaging.

Resumen
Until recently, the only realistic form of treatment available to patients in end stage heart failure was transplantation. In the last few years, the possibility of diverting skeletal muscle from its normal function to perform a cardiac assist role has emerged as a potential alternative to transplant surgery. The introduction of an Skeletal Muscle Ventricle (SMV) to the circulation is a potential long-term hazard, as the patient's blood comes into contact with the non-endothelialised surfaces of the wall of the new ventricle and the connecting conduits. This may trigger a cascade of events lea

Resumen
The intensive care unit treats the most critically ill patients in the hospital, and as such the clinical staff in the intensive care unit have to deal with complex, time-sensitive and life-critical situations. Commonly, patients present with multiple organ dysfunctions, require breathing and cardiovascular support, which make diagnosis and treatment even more challenging. As a result, clinical staff are faced with processing large quantities of often confusing information, and have to rely on experience and trial and error.

Resumen
Cardiovascular diseases are the leading cause of death worldwide, and are estimated to kill over 17 million people each year, about 31% of all deaths. In the clinic, the first diagnostic procedure for a suspected cardiac abnormality is often acquisition of an electrocardiogram (ECG), which measures the electrical potential of the heart at the body surface. Understanding the mechanisms underlying generation of the ECG waveforms is crucial for optimal clinical benefit. Computer simulations possess several strengths as a tool to gain this understanding, particularly in terms of human-specificity,

The morbidity of and the mortality from cardiac disease are higher in diabetic patients.

The mechanism(s) involved in this diabetic cardiomyopathy is still unclear, but one defect appears to occur in the alpha₁-adrenoceptor system.

Resumen
Hypothermia alters myocardial electrophysiology and can result in ventricular arrhythmias. Therapeutic hypothermia is used to mitigate neurological injury after cardiac arrest with moderate hypothermia (32-340C) to minimise the risk ventricular arrhythmias. The mechanisms responsible remain poorly understood and we thus sought to examine the arrhythmogenicity of hypothermia in a large animal model. Ten sheep were cooled systemically using an extracorporeal circuit. Surface 12 lead ECGs, and epicardial and transmural potentials (N=220) were recorded. Potentials were recorded during sinus rhyt
