Does the guardian system detect abnormal heart rhythms?

Does the guardian system detect abnormal heart rhythms?

Yes and much more: The angelmed guardian system is an implantable st segment monitor. It is designed to detect an imminent heart attack or decrease in blood flow to the heart with exercise. It will also detect changes in the heart rhythm such as atrial fibrillation or premature ventricular contractions. ...Read more

Rhythm (Definition)

Rhythm "any regular recurring motion, symmetry may be generally defined as a movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions, this general meaning of regular recurrence or pattern in time may be applied to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything microseconds ...Read more

Why does?An electrical shock delivered to the heart?Correct abnormal heart rhythms?

Rebooting the system: Our heart works through electrical pathways. If these pathways get out of sync or mixed up then sometimes cardioversion or defibrillation a.K.A. "reboot of the system" can get the electricity back in sync. ...Read more

How does electrical stimulation of the heart coordinate the cardiac cycle again?

Reset own pacemaker: Assuming query is about cardioversion. There are hierarchies of pacemaker cells in the heart. Fastest one usually takes over. Normal sinus node, then av node or "junction", then purkinje or ventricular pacemakers, in that approximate order. If there is a rhythm disturbance involving a faster abnormal rhythm, an electrical pulse carefully delivered can reset, and allow the fastest normal pacer. ...Read more

What is an electrical shock delivered to the heart to correct abnormal heart rhythms called?

Cardioversion-defib: An implantable aicd has cardioversion and defibrillation capabilities. However, usually, it delivers a defibrillatory shock when it detects a dangerous rhythm. Of course, the energy is much lower since less tissue needs to be penetrated (the electrical lead goes directly into the heart). ...Read more

What does severe hypoxemia affect the heart's electrical system?

What does severe hypoxemia affect the heart's electrical system?

Hypoxemia: Severe hypoxemia changes the depolarization characteristics of the myocardial cells and can cause severe problems. The academia which often happens with low oxygen can cause hyperkalemia which can cause severe bradycardia and other electrophysiologic abnormalities. ...Read more

What are the uses of electrocardiogram .Does it can detect heart failure ..?

What are the uses of electrocardiogram .Does it can detect heart failure ..?

No: Heart failure is a clinical diagnosis - you have certain symptoms, such as shortness of breath and easy fatigue-ability, and if they are connected to abnormal heart function you may be diagnosed with heart failure. An ECG usually discloses underlying heart rhythm disturbances or the presence of coronary artery blockages, though much more can be detected. ...Read more

Can you explain how the heart valves opening/closing is synchronized with the heart's pacemaker firing?

One causes the other: The pacemaker of the heart initiates an electrical impulse that spreads across the upper chambers and causes them to contract. Contraction of the atria pushes the atrioventricular valves open. Subsequently, the electrical impulse is transmitted to the lower chambers of the heart. The contraction of the ventricles opens the semilunar valves; at the same time the atrioventricular valves close. ...Read more

What is an abnormal heart rate that can impair cardiac output called?

What is an abnormal heart rate that can impair cardiac output called?

Cardiac Output: Cardiac output equals stroke volume x heart rate. That means if the heart rate goes up the cardiac output will go up. The stroke volume is how much the heart pumps out with each contraction. That can go down if the heart rhythm is off like in atrial fibrillation. ...Read more

30 xtrabeats in 48 hours, doc said were normal, does that mean they were going through the av node or is ectopic beats directly to ventricles?

30 xtrabeats in 48 hours, doc said were normal, does that mean they were going through the av node or is ectopic beats directly to ventricles?

Extra beats: cannot tell without an electrophysiology study to MAP the electrical activity of the heart. But as your heart doctor told you it is normal and nothing to worry about. Wondering why you had a holter study to begin with? If it was normal and one is trying to determine cause of irregular or rapid heart beat, may need further evaluation. ...Read more

How does electrical stimulation of the heart coordinate the overall cardiac cycle?

Millisecond timing: The 2 atria act as reservoirs for returning blood; the 2 ventricles are the "pumpers". The 4 chambers must be coordinated with millisecond timing to maximize the amount of blood pumped (cardiac output). This is done by a network of specialized cells which are found in tracts or bundles that conduct a micro-electrical current to time motion. A gross analogy: think of the distributor in your car. ...Read more

How high does the troponin result be, to signal a heart attack?

How high does the troponin result be, to signal a heart attack?

It depends: In the proper setting with chest pain & abnormal electrocardiogram an elevated troponin (highly sensitive version) can indicate heart damage. However there are other possible explanations for an elevated level. These include congestive heart failure, pulmonary embolism (blood clot in the lungs) or kidney failure. The pattern of the elevation over time is also useful. ...Read more

When is ?Digitalis? Used to cure abnormal heart rhythms?

Never: Digitalis is used to control the ventricular rates of some abnormal fast atrial arrhythmias or svt. In atrial fibrillation it is utilized to control the fast rate. It does not "cure" the problem nor does it actually prevent the atrial arrhythmias, as antiarrhythmic medications would. ...Read more

How do you define abnormal heart rhythms?

How do you define abnormal heart rhythms?

Many different types: A normal heart beat is regular like a clock ticking. There are many different types of abnormal heart rhythms. The heart rhythm could be either too fast, too slow or have some type of irregularity or skipping. Some of these abnormal rhythms are not serious. Some irregular rhythms are potentially dangerous. The best way to check is call you doctor and have an ekg or heart monitor performed. ...Read more

Do abnormal heart rhythms decrease blood delivery?

Do abnormal heart rhythms decrease blood delivery?

Depends: It depends on the type of dysrhythmia and the rate. For example, atrial fibrillation with a heart rate in the 70-80s may cause no symptoms at all. A rate in the 150's may decrease blood pressure because there is not adequate time for the heart to fill between beats. A heart rate lower than 30 may cause a low blood pressure because the slow rate. Symptoms often relate to total cardiac output. ...Read more

Several: An EKG to see what the exact rhythm is and to look for other abnormalities. A history and physical examination. You may have a heart murmur or appear pale if you have anemia for instance. Blood tests to exclude anemia or an overactive thyroid gland for instance. A holter monitor to catch and record the abnormal rhythm. An echocardiogram to evaluate heart function and the valves. ...Read more
