Ischaemic heart disease

Physiological Effects of Monomorphic Ventricular Tachycardia Ventricular tachycardia (VT) is a disease of the heart, in which the heart’s normal rhythmic contraction is altered, changing the heart function (Ideker &Walcott, 1993). It is characterized by having a heartbeat that is too fast, although the disease itself is far more complex (Ideker & Walcott, 1993). Ventricular tachycardia often leads to ventricular fibrillation (VF), and together, they are among the most life threatening cardiac…

A cardiovascular surgeon is a complicated job fit for only those who can be under pressure and still work. This kind of doctor in particular is respected and gazed upon, admired for working with such an intricate organ, the heart. These physicians get paid highly, they receive ninety dollars within a single hour. Though such a job is not easy it is in fact a challenge to pursue such a highly educated career. In order for someone to become such a respected doctor they must have multiple years of…

It’s You Or Me. (It’s probably going to be me.) I entered the first house my heart was racing, my palms were sweating, and I was frantic to get in and out. I had never done this before but I was desperate as if this was the last thing I could do to survive. I yelled out “hello!” No one replied I did a quick look of the downstairs and then slowly and quietly went upstairs all I could hear was my heart beating out of my chest. I was looking for one thing and one thing only and that was gold,…

• Muscle tissue: Cardiac and skeletal muscle Cardiac and skeletal muscles have very few similarities and many differences. Firstly cardiac muscles location is found in the heart and the skeletal muscle location is found all over the body in every single bone present in humans. The similarities of cardiac and skeletal to start with is that they are both striated muscle structured, but cardiac is lightly striated and skeletal is heavily striated. Now to describe the differences, initially…

muscle you gain, which makes you burn calories faster and easier. As you become stronger, then you will not easily fatigue. Building muscle can help you as you age. Strength training helps your body from things like back pain, arthritis, obesity, heart disease and diabetes. Strength training helps you to do the usual things as athletes, jump higher, run faster, and increase your endurance. Weight training is good for athletes no matter how old you are. Strength training…

The human body has approximately 5 liters of blood in circulation at any given time. Therefore, when a blood vessel is ruptured or damaged, as a result of an injury, it is vital that the loss of blood is minimalized. The process that enables this is called haemostasis. In terms of Rosemary’s ‘quite bad’ cut on her finger, as a result of slicing it with a kitchen knife, her body will react quickly by following all three stages of haemostasis. We can assume this as a result of the bleeding taking…

perfusion? a) Heart Rate b) Contractility c) High blood pressure d) Platelet aggregation and thrombosis Answer: D Answer Rationale: A. (Incorrect) Heart rate and coronary perfusion is not correlated. An increase or decrease in heart rate along does not necessarily impact the coronary perfusion. In most cases, it is the vasodilation and vasoconstriction in either health or platelet aggregated vessels that impact coronary perfusion. B. (Incorrect) Any change in the contractility of the heart…

Atherosclerosis is a disease where arteries thicken as cholesterol builds-up on their walls. A chronic inflammatory response in the arterial wall by the macrophage accumulation, promoted by low-density lipids.5 It is caused by the formation of multiple plaques within the arteries that can lead to stroke and myocardial infarction. Macrophages tend to rupture plaques by releasing lytic???? enzymes that break plaques in the arteries. Biomarkers such as plasma lipid estimation and myeloperoxidase,…

Discussion Warm up exercise normally results in an elevated blood, and probably muscle lactate concentration has the potential to increase the aerobic energy turnover in the following high intensity exercise. The reduced oxygen deficit is related with the reduction in both the depletion of intramuscular PCr stores and the rate at which lactic acid is produced, which is probably caused by overtraining or fatigue ( Jones, Andrew M. and Koppo, Katrien and Burnley, Mark, 2003). One of the factors…

C.R. Ethier, analyzes mass transport patterns in a realistic right coronary artery model and looks at what affects mass transport from blood to the wall of the artery. The researchers were looking for any relationships between atherosclerosis, a disease of the arteries characterized by built up plaque on their inner walls, and hemodynamic and mass transport patterns. To begin, a model of the right coronary artery of a forty-seven year old woman, who did not die from cardiovascular related…
