What else can I help you with?
What is the term for three or more premature ventricular complexes occurring in a row at a rate of more than 100 beats a minute?
that looks like 2 different things. 4 or more pvc's is considered "a run of vtach" the other part would depend on the rhythm before the vtach... ex. sinus tachycardia with a run of vtach
What part of the conduction system of the heart wraps around in the outer walls of the ventricular?
purkinje fibers
Why Fever causes tachycardia with head injury patient?
Fever in a head injury patient can lead to tachycardia as part of the body's systemic response to infection or inflammation. Increased body temperature raises metabolic demands, prompting the heart to pump more blood to meet the needs of tissues. Additionally, the release of stress hormones, such as adrenaline, in response to both fever and injury can further increase heart rate. This combination of factors contributes to the observed tachycardia.
Which artery supplies the anterior ventricular walls and laterodorsal part of the left side of the heart?
Left coronary artery
The hearts apex rests on what?
The apex is the lowest part of the heart which is responsible for ventricular contraction. It points downward, and rests on the diaphragm.
What is trachea cardia?
I think what you mean is tachycardia, which is faster than normal heart ranges. tachys:rapidor accelerated - kardia or cardia: of the heart. The Trachea is part of your lower airway system.
Where are autorhythmic cells located in the heart?
There are two pacemakers in the heart. One (which is the main pacemaker of the heart) can be found in the upper right-most part of the right atrium and the other one can be found in the center most part of the heart, inside the atrio-ventricular wall.
What does the medical abbreviation PVC mean?
PVC in medical terms is a premature ventricular contraction.Premature Ventricular Contractions. See the related link for more information.Usually PVC stands for Premature Ventricular Contractions. Which basically means the ventricles (lower part of the heart) is contracting too soon.
Why does stress cause tachycardia?
Stress triggers the release of stress hormones like adrenaline, which can increase heart rate. This response is part of the body's "fight or flight" mechanism, preparing the body to respond quickly to perceived threats. Tachycardia is the body's way of increasing blood flow and oxygen to your muscles and organs to help you deal with the stressful situation.
What is sinus rhythm with occasional premature ventricular complexes?
Sinus rhythm, the natural beating of the heart begins in the sinoatrial (or sinus) node and is located in the wall of the right atrium. Occasional premature ventricular complexes are abnormal heartbeats that disrupt the regular rhythm of the heart. The irregular heartbeats begin in one of the ventricles in the lower part of the heart.
What part of an ECG represents ventricular depolarization?
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
What is the ventricular contraction period?
The ventricular contraction period refers to the phase of the cardiac cycle when the ventricles of the heart are contracting to pump blood out to the lungs and the rest of the body. This stage is also known as systole. It is an essential part of the overall heart function in maintaining blood circulation throughout the body.
