key concept notes and diagrams for cardiac arrhythmias. included: atrial fibrilation, supraventricular tachycardia, ventricular tachycardia and ventricular fibrilation
What are Ventricular Tachycardia and Ventricular Fibrillation? Ventricular Tachycardia and Ventricular Fibrillation are both a group of conditions where the heartbeat is irregular, too slow, or too fast. Such conditions are known as Heart arrhythmia.
Atrial fibrillation (Afib) and ventricular fibrillation (Vfib) are both a type of abnormal heart rhythm (arrhythmia). Atrial fibrillation is caused by irregular electrical impulses in the atria and ventricular fibrillation is caused by irregular electrical impulses in the ventricles. Symptoms of both Afib and Vfib are shortness of breath, dizziness, nausea, and chest pain.

Presently, resuscitation is guided by a standardised protocol which includes only rhythm detection for decision support. We suggest an extended diagnostics, which is primarily based on the ventricular fibrillation (VF) ECG and provides information on the physiological status of the patient. Thereby, the removal of artefacts resulting from cardiopulmonary resuscitation (CPR) becomes desirable. The performance of different VF ECG parameters is discussed with respect to their capability to predict the success of subsequent defibrillation attempts. Two new algorithms for CPR artefact removal are presented which are both based on state-space models and Kalman recursions. The first algorithm models the CPR part of a corrupted ECG signal as a stochastically changing seasonal time series with an optionally time-dependent period. The second algorithm estimates the CPR part by an adaptive regression on lagged copies of some reference signal. The ECG parameters and artefact removal algorithms are optimised and evaluated on human and animal data. The thesis finally contains measurement results and a corresponding analysis of the waveforms of various modern external biphasic defibrillators.
Background: Recent data demonstrate promising effects on left ventricular dysfunction and left ventricular ejection fraction (LVEF) improvement following ablation for atrial fibrillation (AF) in patients with heart failure. We sought to study the relationship between LVEF, New York Heart Association class on presentation, and the end points of mortality and heart failure admissions in the CASTLE-AF study (Catheter Ablation for Atrial Fibrillation With Heart Failure) population. Furthermore, predictors for LVEF improvement were examined. Methods: The CASTLE-AF patients with coexisting heart failure and AF (n=363) were randomized in a multicenter prospective controlled fashion to ablation (n=179) versus pharmacological therapy (n=184). Left ventricular function and New York Heart Association class were assessed at baseline (after randomization) and at each follow-up visit. Results: In the ablation arm, a significantly higher number of patients experienced an improvement in their LVEF to >35% at the end of the study (odds ratio, 2.17; P<0.001). Compared with the pharmacological therapy arm, both ablation patient groups with severe (<20%) or moderate/severe (≥20% and <35%) baseline LVEF had a significantly lower number of composite end points (hazard ratio [HR], 0.60; P=0.006), all-cause mortality (HR, 0.54; P=0.019), and cardiovascular hospitalizations (HR, 0.66; P=0.017). In the ablation group, New York Heart Association I/II patients at the time of treatment had the strongest improvement in clinical outcomes (primary end point: HR, 0.43; P<0.001; mortality: HR, 0.30; P=0.001). Conclusions: Compared with pharmacological treatment, AF ablation was associated with a significant improvement in LVEF, independent from the severity of left ventricular dysfunction. AF ablation should be performed at early stages of the patient’s heart failure symptoms.

The heart monitor alarm suddenly screamed as the patient's EKG pattern abruptly changed to ventricular fibrillation. \"Code Blue!\" Dr. Singh screamed, \"Get the crash cart in here, now!\" THUMP! The convulsive thrash of his patient after each defibrillation attempt was beginning to be too much for Dr. Brady. THUMP! He didn't know if he could stand the helpless feeling any longer. Attempt after attempt failed to resuscitate Mrs. Winter. He wanted to scream or run away, but continued in his efforts to save his patient. He prayed he was just going to wake up from this nightmare, hug his wife, and be thankful that this surrealistic scene didn't exist. But that simply wasn't going to happen. What began as sixty seconds of shock and terror, soon became forty minutes of futility. After trying everything they could think of to restore a normal heart rhythm to the patient's lifeless body, Dr. Singh called off the code. Jessie Winter was dead! This action-packed mystery will take you from the operating room to the courtroom as Dr. Brady searches for the truth behind his patient's unexpected death, and the resulting malpractice and manslaughter trials.

Atrial fibrillation (AFib) and ventricular fibrillation (VFib) are both heart conditions that are referred to as arrhythmias. Learn the differences and similarities of these conditions, including their causes, symptoms, and treatment.
Ventricular fibrillation (V-fib or VF) is when the heart quivers instead of pumps due to disorganized electrical activity in the ventricles. It results in cardiac arrest with loss of consciousness and no pulse. This is followed by irreversible death in the absence of treatment. Ventricular fibrillation is found initially in about 10% of people in cardiac arrest. Ventricular fibrillation can occur due to coronary heart disease, valvular heart disease, cardiomyopathy, Brugada syndrome, long QT syndrome, or intracranial haemorrhage. Diagnosis is by an electrocardiogram (ECG) showing irregular unformed QRS complexes without any clear P waves. An important differential diagnosis is torsade's de pointes. Treatment is with cardiopulmonary resuscitation (CPR) and defibrillation. Biphasic defibrillation may be better than monophasic.

Smarty Saver Semi-Automatic Defibrillator, a basic and affordable defibrillatior that is easy to use. It can be easily operated by anyone in the medical field, such as ambulance personnel and the non-medical field such as the general public. Reliable and durable, capable of tackling challenges in various severe environments. The Smarty Saver can deliver one or more defibrillating shocks on adult or paediatric patients affected by ventricular fibrillation or ventricular tachycardia, by means of a thorax impedance-compensated, biphasic truncated exponential discharge (BTE).The Semi-Automatic model analyses the patient's ECG and if a shockable rhythm is detected it automatically starts charging the reservoir capacitor. The AED vocal message will suggest the operator to press the shock button to deliver the defibrillating shock.The phase following the defibrillation, that is the Cardiopulmonary Resuscitation, will be guided by voice prompts and the metronome marking the various cycles of compressions and insufflations.
