  2. Second-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Second-degree_atrio...

    Avoidance of AV-nodal-blocking medication, pacemaker. Second-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart. It is a conduction block between the atria and ventricles. The presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct ...

  3. Atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Atrioventricular_block

    Specialty. Cardiology. Atrioventricular block ( AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired. Normally, the sinoatrial node (SA node) produces an electrical signal to control the heart rate.

  4. Pulseless electrical activity - Wikipedia

    en.wikipedia.org/wiki/Pulseless_electrical_activity

    Cardiology. Pulseless electrical activity ( PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [ 1] and about 50% of in-hospital cardiac arrests. [ 2]

  5. Heart block - Wikipedia

    en.wikipedia.org/wiki/Heart_block

    Heart block. Heart block ( HB) [ 1] is a disorder in the heart 's rhythm due to a fault in the natural pacemaker. [ 2] This is caused by an obstruction – a block – in the electrical conduction system of the heart. Sometimes a disorder can be inherited. Despite the severe-sounding name, heart block may cause no symptoms at all in some cases ...

  6. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Use of real time monitoring of the heart in an intensive care unit in a German hospital (2015), the monitoring screen above the patient displaying an electrocardiogram and various values of parameters of the heart like heart rate and blood pressure. Electrocardiography is the process of producing an electrocardiogram ( ECG or EKG[ a] ), a ...

  7. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    Rhythm interpretation is an important part of healthcare in Emergency Medical Services ( EMS ). Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia.

  8. Junctional rhythm - Wikipedia

    en.wikipedia.org/wiki/Junctional_rhythm

    Junctional rhythm. Junctional rhythm also called nodal rhythm[ 2] describes an abnormal heart rhythm resulting from impulses coming from a locus of tissue in the area of the atrioventricular node (AV node), [ 3] the "junction" between atria and ventricles. Under normal conditions, the heart's sinoatrial node (SA node) determines the rate by ...

  9. Algorithm spots abnormal heart rhythms with doctor-like accuracy

    For example, two forms of the arrhythmia known as second-degree atrioventricular block look very similar, but one requires no treatment while the other requires immediate attention."
