EASY WAY TO REMEMBER: THIRD DEGREE HEART BLOCK (COMPLETE HEART BLOCK)

-

THIRD DEGREE HEART BLOCK (BASICS)

ALSO CALLED AS COMPLETE HEART BLOCK . 

WHEN ATRIAL CONTRACTION IS NORMAL BUT NO BEATS ARE CONDUCTED TO THE VENTRICLES.

THIS MAY OCCUR IN PATIENT WITH MYOCARDICAL INFARCTION OR IT MAY BE CHRONIC (USUALLY DUE TO FIBROSIS AROUND THE BUNDLE OF HIS).

LET'S MAKE IT SIMPLE: 1. REGULAR  P-P  INTERVAL. 

                                                 2. REGULAR  R-R  INTERVAL.

                                                 3. MORE P WAVES ARE PRESENT THAN QRS COMPLEXES.

NOTE: NO RELATIONSHIP BETWEEN P WAVES AND QRS COMPLEXES, BUT AS I MENTIONED SAME NUMBER OF BIG BOX IN-BETWEEN  (P-P INTERVAL AND R-R INTERVAL)

EASY WAY TO REMEMBER: BUNDLE BRANCH BLOCK

 ECG:  BUNDLE BRANCH BLOCK (BASICS)  THERE ARE 3 TYPES OF BBB( RIGHT, LEFT AND COMPLETE) EASY WAY TO FIND OUT BUNDLE BRANCH BLOCK : IF YOU NOTICED  (BUNNY EARS FORMATION OR M SHAPE WAVES IN LEADS) THEN WE HAVE TO FIND OUT WHICH LEADS WHETHER IT'S LEFT OR RIGHT FOR EXAMPLE: RIGHT BBB ( BEST SEEN IN LEADS V1,V2,V3)                               LEFT BBB ( BEST SEEN IN LEADS V4,V5,V6) RIGHT BBB INDICATES PROMBLEMS IN THE RIGHT SIDE OF THE HEART AND LEFT BBB INDICATES LEFT SIDE. RIGHT BUNDLE BRANCH BLOCK: WE CAN NOTICE M-SHAPED OR BUNNY EARS FORMATON WAVES IN LEADS :V1,V2,V3 (HERE YOU CAN SEE M-SHAPED WAVES IN V1,V2,V3) SO, IT IS RIGHT BBB LEFT BUNDLE BRANCH BLOCK: WE CAN NOTICE M-SHAPED OR BUNNY EARS FORMATION WAVES IN LEADS: VL,   V4,V5,V6 ( HERE YOU CAN SEE M-SHAPED WAVES IN LEADS:VL,V5,V6) SO, IT IS LEFT BBB COMPLETE BUNDLE BRANCH BLOCK: IF YOU SEE M-SHAPED WAVES IN LEDS V1-V6 ON BOTH RIGHT AS WELL LEFT IT INDICATES COMPLETE BBB

EASY WAY TO REMEMBER: WPW SYNDROME

 WOLFF-PARKINSON-WHITE SYNDROME (WPW) BASICS SIMPLE CONCEPT:  PR-INTERVAL (SHORT).                                    DELTA WAVE.                                    QRS COMPLEX (LONG) OVERVIEW: THE ONLY NORMAL ELECTRICAL CONNECTION BETWEEN THE ATRIA AND VENTRICLES IS THE HIS BUNDLE  . SOME PEOPLE, HOWEVER, HAVE AN EXTRA (OR) "ACCESSORY" CONDUCTING BUNDLE, A CONDITION KNOWN AS THE WPW SYNDROME. THE ACCESSORY BUNDLES FORM A DIRECT CONNECTION BETWEEN THE ATRIUM AND THE VENTRICLE, USUALLY ON THE LEFT SIDE OF THE HEART, AND IN THESE BUNDLES THERE IS NO (AV-NODE) TO DELAY CONDUCTION. A DEPOLARIZATION WAVE THEREFORE  REACHES THE VENTRICLE EARLY AND PRE-EXCITATION OCCURS. PR-INTERVAL SHORT, AND THE QRS COMPLEX SHOWS AN EARLY SLURRED UPSTROKE CALLED A "DELTA WAVE". THE SECOND PART OF QRS IS NORMAL, AS CONDUCTION THROUGH THE HIS BUNDLE CATCHES UP WITH THE PRE-EXCITATION. NOTE:  SINUS RHYTHM, RIGHT AXIS DEVIATION, SHORT PR-INTERVAL.              SLURRED UPSTROKE OF THE QRS COM

 LEFT AXIS DEVIATION SIMPLE CONCEPT:  QRS-COMPLEX : (LEAD-1) AND (LEAD aVL) - [POSITIVE]                                                                   : (LEAD- 2, 3, aVF) - [NEGATIVE] RIGHT AXIS DEVIATION SIMPLE CONCEPT:  QES COMPLEX : (LEAD-1) AND (LEAD aVL) - [NEGATIVE] {S-WAVE GREATER THAN R-WAVE}.                                                                 : (LEAD- 2, 3, aVF) - [POSITIVE] CAUSES OF AXIS DEVIATION:  RIGHT AXIS DEVIATION: 1) NORMAL VARIANT-TALL THIN PEOPLE. 2) RIGHT VENTRICULAR HYPERTROPHY. 3) LATERAL MYOCARDIAL INFARCTION ( PERI-INFARCTION BLOCK). 4) WPW SYNDROME. 5) LEFT POSTERIOR FASCICULAR BLOCK. LEFT AXIS DEVIATION: 1) LEFT ANTERIOR HEMIBLOCK. 2) WPW SYNDROME. 3) INF. MI (PERI-INFARCTION BLOCK) 4) VENTRICULAR TACHYCARDIA.
