If the electrical axis is between -30° and -90° this is considered left axis deviation. If the electrical axis is between +90° and +180° this is considered right axis deviation (RAD). RAD is an ECG finding that arises either as an anatomically normal variant or an indicator of underlying pathology.
When left bundle-branch block (LBBB) is accompanied by right axis deviation (RAD), the rare combination is considered to be highly suggestive of dilated or congestive cardiomyopathy. [29] [30] Echocardiogram shows left ventricular dilatation with normal or thinned walls and reduced ejection fraction.
Right ventricular hypertrophy is the intermediate stage between increased right ventricular pressure (in the early stages) and right ventricle failure (in the later stages). [11] As such, management of right ventricular hypertrophy is about either preventing the development of right ventricular hypertrophy in the first place, or preventing the ...
The ventricular beats typically have a right axis deviation. Multiple morphologies of ventricular tachycardia may be present in the same individual, suggesting multiple arrhythmogenic foci or pathways. Right ventricular outflow tract (RVOT) tachycardia is the most common VT seen in individuals with ACM.
Right atrial enlargement (RAE) is clinically significant due to its prevalence in diagnosing supraventricular arrhythmias. Further, early diagnosis using risk factors like RAE may decrease mortality because patients with RAE are at 9x more risk of arrhythmias and other cardiac conditions compared to their healthy counterparts.

Pre-excitation may not cause any symptoms but may lead to palpitations caused by abnormal heart rhythms. It is usually diagnosed using an electrocardiogram, but may only be found during an electrophysiological study. [2] The condition may not require any treatment at all, but symptoms can be controlled using medication or catheter ablation.
Right and left ventricular end-systolic and end-diastolic volume indices, ejection fractions, and the existence of aneurysm generating obstructive outflow are all parameters seen in this research. Exercise intolerance, heart failure signs and symptoms, syncope, and prolonged ventricular tachycardia are all possible symptoms.
Right ventricular hypertrophy and right axis deviation on ECG Cyanosis , tachypnea and dyspnea , since the overloaded pulmonary circuit can cause pulmonary edema Cottage-loaf sign , that is, chest X-ray appearance similar to a cottage loaf, also known as the 'snow man' sign or 'figure of 8' sign.
