Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms

of the signals depend upon the position of the electrodes (Brown‚ 1999) (Conover‚ 1992). The SA node produces the pacemaker potential and if this reaches the threshold then an action potential is generated. There are five stages involved during cardiac action potentials‚ during these stages there is a flow of ions through

Global Cardiac Biomarkers Market 2014-20180280035A cardiac biomarker is defined as a measurable substance that is used as an indicator for diagnosis and risk stratification related to CVDs such as ACS‚ coronary syndromes‚ MI‚ and HF. Some of the cardiac biomarkers are CK-MB‚ troponins (cTnI and cTnT)‚ BNP‚ NT-proBNP‚ GFAP‚ H-FABP‚ LDH isoenzymes‚ D-Dimer‚ IMA‚ MPO‚ myoglobin‚ and sCD40L. Cardiac biomarker assays help medical professionals in understanding and differentiating between MI and angina

Global Cardiac POC Testing Devices Market 2014-2018 Cardiac POC tests are medical blood tests that include cholesterol and coagulation testing. Cardiac POC tests include troponin and BNP tests that are used to diagnose cardiovascular conditions such as acute myocardial infarction‚ coronary syndromes‚ and heart failure. These tests help to detect the enzymes released during heart failure and in other critical cardiac conditions that release creatine kinase‚ troponin‚ LDH isoenzymes‚ and BNP. These

This paper examines some of the ethical dilemmas posed to the medical community by the practice of organ donation after cardiac death (DCD) and whether it violates any of the basic ethical principles of medicine. Cardiac death can only be declared on the basis of cardiopulmonary criteria of permanent cessation of circulatory and respiratory function and not on the basis of neurological criteria of irreversible loss of all functions of the entire brain‚ which is used to declare brain death.
