In the case of post-synaptic neurons, the reversal potential is the membrane potential at which a given neurotransmitter causes no net current flow of ions through that neurotransmitter receptor's ion channel.AsystoleLong-acting beta-adrenoceptor agonist: Long-acting beta-adrenoceptor agonists (LABAs, more specifically β2-agonists) are usually prescribed for moderate to severe persistent asthma patients or patients with chronic obstructive pulmonary disease (COPD). They are designed to reduce the need for shorter-acting β2-agonists such as salbutamol, as they have a duration of action of approximately 12 hours in comparison with the 4- to 6-hour duration of salbutamol, making them candidates for sparing high doses of corticosteroids or treating nocturnal asthma and providing symptomatic improvement in patients with COPD.Sarcalumenin: Sarcalumenin is a protein that in humans is encoded by the SAR gene.Inotrope: An inotrope (etymology and pronunciation) is an agent that alters the force or energy of muscular contractions. Negatively inotropic agents weaken the force of muscular contractions.Automated ECG interpretation: Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.Kennel clubMyocyteElectrocardiography in myocardial infarctionInterbeat interval: Interbeat interval is a scientific term used in the study of the mammalian heart.Cardiac glycoside: Cardiac glycosidesSingh, B. and Rastogi, R.Periodic current reversalCell growth: The term cell growth is used in the contexts of cell development and cell division (reproduction). When used in the context of cell division, it refers to growth of cell populations, where a cell, known as the "father cell", grows and divides to produce two "son cells" (M phase).Mydicar: Mydicar is a genetically targeted enzyme replacement therapy being studied for use in patients with severe heart failure. It is designed to increase the level of SERCA2a, a sarcoplasmic endoplasmic reticulum calcium (Ca2+) ATPase found in the membrane of the sarcoplasmic reticulum (SR).New Zealand rabbitRyanodine receptor: Ryanodine receptors (RyRs) form a class of intracellular calcium channels in various forms of excitable animal tissue like muscles and neurons. There are three major isoforms of the ryanodine receptor, which are found in different tissues and participate in different signaling pathways involving calcium release from intracellular organelles.Yashoda HospitalsBeta-adrenergic agonist: Beta-adrenergic agonists or Beta-agonists are medications that relax muscles of the airways, which widens the airways and results in easier breathing. They are a class of sympathomimetic agents which act upon the beta adrenoceptors.Voltage-dependent calcium channel: Voltage-dependent calcium channels (VDCC) are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g.Coronary ischemia: Coronary ischemia is a medical term for not having enough blood through the coronary arteries. Coronary ischemia is linked to heart disease as well as heart attacks.CaffeineHeart transplantationProtein turnover: Protein turnover is the balance between protein synthesis and protein degradation. More synthesis than breakdown indicates an anabolic state that builds lean tissues, more breakdown than synthesis indicates a catabolic state that burns lean tissues.CardiomyopathyClinical electrophysiology: Clinical electrophysiology is the application of electrophysiology principles to medicine. The two main branches of this discipline are electrotherapy and electrophysiologic testing (EEG, electromyography, etc.Sodium channel: Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. They are classified according to the trigger that opens the channel for such ions, i.Gross pathology: Gross pathology refers to macroscopic manifestations of disease in organs, tissues, and body cavities. The term is commonly used by anatomical pathologists to refer to diagnostically useful findings made during the gross examination portion of surgical specimen processing or an autopsy.Proarrhythmia: Proarrhythmia is a new or more frequent occurrence of pre-existing arrhythmias, paradoxically precipitated by antiarrhythmic therapy, which means it is a side effect associated with the administration of some existing antiarrhythmic drugs, as well as drugs for other indications. In other words, it is a tendency of antiarrhythmic drugs to facilitate emergence of new arrhythmias.Concentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.Mature messenger RNA: Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, it consists exclusively of exons, with all introns removed.Electrical conductivity meterCongenital heart defectAortic pressure: Central aortic blood pressure (CAP or CASP) is the blood pressure at the root of aorta. Studies have shown the importance of central aortic pressure and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors.Echogenic intracardiac focus: Echogenic intracardiac focus (EIF) is a small bright spot seen in the baby’s heart on an ultrasound exam. This is thought to represent mineralization, or small deposits of calcium, in the muscle of the heart.MYH7: MYH7 is a gene encoding a myosin heavy chain beta (MHC-β) isoform (slow twitch) expressed primarily in the heart, but also in skeletal muscles (type I fibers). This isoform is distinct from the fast isoform of cardiac myosin heavy chain, MYH6, referred to as MHC-α.Fractional sodium excretion: The fractional excretion of sodium (FENa) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.End-diastolic volume: In cardiovascular physiology, end-diastolic volume (EDV) is the volume of blood in the right and/or left ventricle at end load or filling in (diastole) or the amount of blood in the ventricles just before systole. Because greater EDVs cause greater distention of the ventricle, 'EDV is often used synonymously with preload, which refers to the length of the sarcomeres in cardiac muscle prior to contraction (systole).Concentric hypertrophy: Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, in which the walls of the organ are thickened and its capacity or volume is diminished.Voltage-gated potassium channel database: VKCDB (Voltage-gated potassium Channel DataBase) is a database of functional data about the voltage-gated potassium channels.Calsequestrin: Calsequestrin is a calcium-binding protein of the sarcoplasmic reticulum. The protein helps hold calcium in the cisterna of the sarcoplasmic reticulum after a muscle contraction, even though the concentration of calcium in the sarcoplasmic reticulum is much higher than in the cytosol.
