I received the Sacrament of the Anointing of the Sick today; why?

You may have read earlier that I spent this morning in the ER with an uncomfortable bout of A-fib, an irregular heartbeat.  Now I've been dealing with this for years but today's incident was, for me, extreme.  While most of my incidents last from 1-5 minutes, occasionally I will have a spell lasting 20, 30, even 45 minutes.  These are rare.  My particular spells have never caused fainting or shortness of breath; all possible with A-fib.  Today I experienced a 2 hour incident and I was light headed.  Fortunately my wife drove me to the ER after we placed a call to my Pastor that I would not be at my assigned Mass.  Not soon after I arrived at the ER, there was my Pastor, Fr. Rodney Bourg, and he offered prayers and encouragement and then I received the Sacrament known as the Anointing of the Sick.  Now many Catholics remember this Sacrament as the Last Rites or Extreme Unction.  The article below will explain in great detail the Sacrament, it's roots in Scripture, and how it is used among the Catholic faithful.

The Sacrament of the Anointing of the Sick

Learn about the practice of the Sacrament of the Sick in the Catholic Church

By Scott P. Richert

Introduction:
Traditionally referred to as Extreme Unction or Last Rites, the Sacrament of the Anointing of the Sick was previously most commonly administered to the dying, for the remission of sins and the provision of spiritual strength and health. In modern times, however, its use has been expanded to all who are gravely ill or are about to undergo a serious operation, and the Church stresses a secondary effect of the sacrament: to help a person recover his health. Like Confession and Holy Communion, to which it is closely linked, the Sacrament of the Anointing of the Sick can be repeated as often as is necessary.
Biblical Roots:
The modern celebration of the Sacrament of the Anointing of the Sick recalls the early Christian use, going back to biblical times. When Christ sent His disciples out to preach, "they cast out many devils, and anointed with oil many that were sick, and healed them" (Mark 6:13). James 5:14-15 ties physical healing to the forgiveness of sins:

Is any man sick among you? Let him bring in the priests of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith shall save the sick man: and the Lord shall raise him up: and if he be in sins, they shall be forgiven him.

Who May Receive the Sacrament?:
Following this biblical understanding, the Catechism of the Catholic Church (para. 1514) notes that:

The Anointing of the Sick "is not a sacrament for those only who are at the point of death. Hence, as soon as anyone of the faithful begins to be in danger of death from sickness or old age, the fitting time for him to receive this sacrament has certainly already arrived."

When in doubt, priests should err on the side of caution and provide the sacrament to the faithful who request it.
The Form of the Sacrament:
The essential rite of the sacrament consists in the priest (or priests, in the case of the Eastern Churches) laying hands on the sick, anointing him with blessed oil (usually olive oil blessed by a bishop, but in an emergency, any vegetable oil will suffice), and praying "Through this holy anointing may the Lord in his love and mercy help you with the grace of the Holy Spirit. May the Lord who frees you from sin save you and raise you up."
When circumstances permit, the Church recommends that the sacrament take place during Mass, or at least that it be preceded by Confession and followed by Holy Communion.
The Minister of the Sacrament:
Only priests (including bishops) can administer the Sacrament of the Anointing of the Sick, since, when the sacrament was instituted during Christ's sending out of His disciples, it was confined to the men who would become the original bishops of the Church.
The Effects of the Sacrament:
Received in faith and in a state of grace, the Sacrament of the Anointing of the Sick provides the recipient with a number of graces, including the fortitude to resist temptation in the face of death, when he is weakest; a union with the Passion of Christ, which makes his suffering holy; and the grace to prepare for death, so that he may meet God in hope rather than in fear. If the recipient was not able to receive the Sacrament of Confession, Anointing also provides forgiveness of sins. And, if it will aid in the salvation of his soul, Anointing may restore the recipient's health.
