Fallot’s Tetralogy Clinical features Symptoms Complications WITH Treatment

Fallot’s Tetralogy Clinical features of Fallot’s Tetralogy Symptoms Complications WITH Treatment it is the commonest congenital cyanotic heart disease. This congenital heart disease consists of ventricular septal defect, pulmonary stenosis, overriding of aorta and right ventricular hypertrophy. When there is moderate PS and small VSD, there is acyanotic Tetralogy of Fallot. As these children survive [...]

Heart Failure Treatment Heart Failure GENERAL PRINCIPLES

Heart Failure Treatment PHARMACOLOGICAL THERAPY Heart failure (HF) is a common clinical syndrome representing the end-stage of a number of different cardiac diseases. Heart failure may result from arrhythmias, heart valve lesions,myocardial infarction, myocardial ischemia, congenital malformation of the heart or great vessels, pericarditis, cardiomyopathy, constrictive or conditions that affect the heart indirectly, [...]

First degree AV block,Second degree AV block (Mobitz type I,Mobitz type Il),Third degree AV block

AV CONDUCTION DISORDERS When AV nodal block occurs the His bundle can generate a heart rate of 40 – 60 beats per minute with normal QRS complexes. If the distal His Purkinje system takes over then the heart rate generated is 25 – 45 beats per minute with wide QRS complexes. This rhythm is [...]

Sick Sinus Syndrome SSS Symptoms Causes Diagnosis with Treatment

Arrhythmia Sick Sinus Syndrome The sick sinus syndrome is a presentation with dizziness, confusion, fatigue, syncope, and heart failure caused by SA node dysfunction. Several electrocardiographical abnormalities caused by a malfunction of the sinoatrial node of the heart, in which there are episodes of tachycardia alternating with episodes of heart block or severely decreased heart [...]

SINUS Bradycardia Bradyarrhythmia Symptoms Causes Diagnosis with Treatment

BRADYARRHYTHMIAS Sinus BRADYCARDIA When the sinus rate is less tha – 60 beats per minute it is called sinus bradycardia,Trained athletes and people doing hard labour, elderly individuals may have resting rate less than 50 beats per mmute. The pacemaker of the heart is the sinoatrial node (SA node). The SA node lies at [...]

Supraventricular tachycardia and Ventricular fibrillation Causes Diagnosis with Treatment

Cardiac Arrhythmias – Supraventricular tachycardia and Ventricular fibrillation – SVT. A rapid, regular tachycardia in which the pacemaker is found in the sinus node, the atria, or the atrioventricular junction, i.e., above the ventricles Distinguishing features of SVT with wide QRS from VT – Triphasic QRS – rsR or qRs . Initial deflection [...]

Ventricular Tachycardia VT Diagnosis Causes Clinical features with Treatment

Cardiac Arrhythmias – Ventricular Tachycardia VT – Three or more consecutive ventricular ectopic complexes (duration greater than 120 ms) occurring at a rate of 100 to 250 beats per minute. Diagnosis of VT (ventricular tachycardia) At least 3 consecutive wide QRS complexes Rate at least 100 per minute Usually rhythm [...]
