Cardiac arrhythmia

Cardiac arrhythmia

Research Purpose

Cardiac arrhythmia is a condition in which contractions of muscle infarction are irregular, and the frequency falls outside the safe range of 60-100 beats per minute (Foxall &Blackburn, 2010). This condition can often be life-threatening, although this is not the case. Normal heart rate is determined by the sinus node. If the sinoatrial node fails to operate properly, it can lead to the activation of secondary centers of excitation and, consequently, to change the heart rate. Another important factor is a pathway from the resort excitation pulse: when the abnormal function or if there are additional pathways may cause arrhythmias.

Research Approach

Cardiac arrhythmias are often detected by non-specific means, such as the auscultation of heart sounds with a stethoscope, and indirectly by examination of peripheral pulse rate. These methods usually cannot diagnose the specific arrhythmia, but give the term heart rate and indicate whether the rhythm is regular or not. Not every electrical activity gives contraction, which would be heard and felt for a pulse wave circuit and, therefore, premature beats or not giving proper cardiac cycle, they are perceived as "abandoned" cramps (Garratt, 2001).

The simplest specific diagnostic test which gives an assessment of heart rhythm is the electrocardiogram (ECG). Detection short-term and unpredictable arrhythmic used Holter monitoring is a continuous 24-hour ECG. It is also used to monitor ECG through a landline or mobile (Podrid, 2001). Different from Holter monitoring that the patient is calling when he feels anxiety is not limited period of 24 hours. An electrocardiogram shows only the electrical activity of the heart. The PEA ECG abnormalities may not be, and the heart does not have cardiac performance.

Bivariate analysis with Cardiac arrhythmia

Correlation analysis in statistics is considered as the most appropriate technique for the bivariate analysis between two variables. This will certainly help in ...
