| Right coronary artery procedures are often associated with sinus arrest, atrioventricular block, idioventricular rhythm, and severe hypotension. |
|
| The ventricular septum and the atrioventricular and semilunar valves were unremarkable. |
|
| Atrial tachycardia with atrioventricular block is typically seen with digoxin toxicity. |
|
| Thus, after delay in the atrioventricular mode, atrial contraction is followed by rapid and coordinated contraction of the ventricles. |
|
| A 29-year-old woman was admitted to the hospital with complete atrioventricular conduction block and severe congestive heart failure. |
|
| In first degree block there is a delay in conduction of the atrial impulse to the ventricles, usually at the level of the atrioventricular node. |
|
| Some of the calcium channel blockers also exert an inhibitory effect on the sinus and atrioventricular nodes, causing the heart rate to slow. |
|
| In some patients the atrioventricular node allows retrograde conduction of ventricular impulses to the atria. |
|
| He had corrective surgery for the atrioventricular septal defect at 3 years of age. |
|
| The beta blocker dose should be reduced if the decrease in heart rate is symptomatic or is associated with hypoperfusion or higher than first-degree atrioventricular block. |
|
| The paradoxical reflex bradycardia may range in severity from simple sinus bradycardia to atrioventricular block, asystole and syncope. |
|
| The left atrioventricular opening is guarded by the mitral, or bicuspid, valve, so named because it consists of two flaps. |
|
| This is the precursor to the heart cushion, which gives rise to the atrioventricular valves and part of the septum. |
|
| Sinus bradycardia, second or third degree atrioventricular block, overt cardiac failure, cardiogenic shock. |
|
| Arrhythmogenic and negative chronotropic and dromotropic effects were observed, as well as extension of atrioventricular conduction times. |
|
| The atrioventricular valves are thin, leaflike structures located between the atria and the ventricles. |
|
| Cardiac disorders: Angina pectoris, atrioventricular block first degree, bundle branch block right, palpitations. |
|
| Subsidence of the ventricular effects may be followed by atrial tachycardia and occasionally by atrioventricular block. |
|
| This acts as the heart's natural pacemaker by conveying electrical impulses to the atrioventricular node, which is located in between the upper and lower chambers. |
|
| Escape rhythms are the result of spontaneous activity from a subsidiary pacemaker, located in the atria, atrioventricular junction, or ventricles. |
|
|
|
| An additional atrioventricular ring has been designed to make fast depolarization of the ventricles. |
|
| The impulse reaches the atrioventricular node, where it's momentarily delayed before it spreads throughout the walls of the ventricles. |
|
| This case highlights atrioventricular block as a potential adverse effect of donepezil. |
|
| Although adenosine is not effective in converting atrial flutter, atrial fibrillation or ventricular tachycardia to sinus rhythm, the transient atrioventricular nodal block produced helps diagnosis of atrial activity. |
|
| Although her medical history revealed no cardiovascular disease, complete atrioventricular block was detected by electrocardiography. |
|
| Congestive heart failure associated with myxomatous degeneration of the left atrioventricular valve in a parakeet. |
|
| Inset, high magnification ventral view of heart showing labeling of atrioventricular valve leaflets. |
|
| Also in the bicaval technique, with the protection of the right atrial anatomy, the atrioventricular valve function is also protected. |
|
| Complete transposition of the atrioventricular valves associated with left ventricular apical hypoplasia. |
|
| Both ventricles had normal systolic function, and both atrioventricular valves were completely competent. |
|
| Patients with atrial fibrillation may develop a rapid ventricular response from withdrawal of the effects of digitalis on the atrioventricular node. |
|
| Classic cardiac pacemaker therapy has now been established for many years, especially for disorders of the sinus node and for atrioventricular blocks. |
|
| The atrioventricular node is also under autonomic control, through which sympathetic stimulation facilitates conduction and parasympathetic stimulation slows conduction. |
|
| The atrioventricular node and bundle of His represent important supraventricular control points in the heart that distribute impulses to the ventricles via the right and left bundle branches. |
|
| These cardiac veins, however, proceed into the atrioventricular grooves anteriorly and posteriorly to form the coronary venous sinus, which opens into the right atrium. |
|
| Maternal sinus bradycardia with abnormal atrioventricular rhythms has also been noted when oxytocin was used concomitantly with cyclopropane anesthesia. |
|
| In conclusion, DI-DORV is a distinct type of functional single ventricle congenital heart disease with variable atrioventricular valve morphology and myocardial architecture. |
|
| Comparative effects of three calcium antagonists, diltiazem, verapamil and nifedipine, on the sinoatrial and atrioventricular nodes. |
|
| It is located in the endocardium of the atrial surface of the right atrioventricular valve. |
|
| Transplacental fetal treatment improves the outcome of prenatally diagnosed complete atrioventricular block without structural heart disease. |
|
|
|
| The tricuspid valve, which is the atrioventricular valve attached to the morphological right ventricle, is affected by a wide range of pathological processes. |
|
| Under these circumstances the sinoatrial node generates an appropriate impulse rate, but the impulses are not transmitted properly through the atrioventricular node and the His bundle. |
|
| Thus, at times sinus rhythm completely captures the ventricles and at other times shows isorhythmic atrioventricular dissociation from an idioventricular rhythm. |
|
| Which parameters describe the electrophysiological properties of successful slow pathway RF ablation in patients with common atrioventricular nodal reentrant tachycardia? |
|
| Origin of blood supply to sinoauricular and atrioventricular node. |
|
| Other conditions, such as inferior myocardial infarction or digitalis toxicity, also may produce block-acceleration atrioventricular dissociation. |
|
| The US Open quarterfinalist, Melanie Oudin was diagnosed with a heart condition last month called atrioventricular nodal re-entrant tachycardia, which required surgery. |
